^I thought these were the parts that were posted in the previous page?

I look for the filter and see if I can get the military discount after I put the newer parts in later this week. Discounts all depend on who works the parts window at the moment.

I found and purchased both the a/c and blower sections as 1 since my blower is the original one hoping for better cooling as well as filtration. After I pulled my original parts out and compared them to the newer, I noticed that the actuator arm that opens and closes the recirculation flap is different with a 3 pin plug vs a 4 pin that mine has. I will have to see what I can do to make it work later this week.

So the crv connector is plug and play after extending the wiring or are the connectors different?

You don't use the CRV evap thermostat. You use/reuse the Civic one. So, connectors = the same. (Unless retrofitting R134a into 92/93 Civic, then connectors different.)

Ok perfect thanks a lot

You can also use the cabin air filter from a 2008-2013 Toyota Tundra, or Toyota Camry. They are the exact same size, and this is what I used in my Civic when I added a cabin air filter.

Currently in the process of gathering all parts to perform on my 92 dx. All e-bay lines will be from a donor 95ex at the local jy. Found a 99si evaperater online for fair price. Just need to find a good compresser now. Just placed an order with honda for all o-rings, receiver/dryer, expansion valve, two caps, and label. Cant wait to have this done!!

BiggieBert

Update: Was able to complete the retrofit in my 92, pulled all lines/compressor/condenser/and harness that plugs into evap/fan etc from a 95 to make it plug and play. Had a few kinks and a few wasted cans of freon, its all sorted and blowing nice and cold. I used the 99 Si evap, had the thermostat mounted in same location as original so no extending wires, just had to relocate position in actual evap.

I just finished retrofitting a 1997 CRV cabin filter into my 1992 Civic. Is it possible to do a swap in a 92 or 93 civic that used R12. Only thing different is that the you will have to use the old 92-93 Civic thermostat in the 97 CRV evaporator assembly. Also, the bolt for the low port side that goes into the evaporator will have to be switched to a M6x35mm bolt. I bought the bolt at the hardware store along with a washer and a locking washer. Other than that, everything else applies when doing the retrofit.

Thanks! I always suspected as much when I test fit the parts on some junkyard cars, but it is great to hear confirmation.

EDIT: Having now done this retrofit also myself (Evap with cabin filter into a 93 Civic with existing R-12 lines), the only additional info I'll add is that the O-rings that I replaced seem to require some that are a little beefier to make up for the different sized lines vs. R-134a. I went with 13x2.5 (top) and 6.8x1.9 (bottom). Pulled a vacuum fine after this. Also used this guy's DIY to test for leaks in the line (and discovered the O-ring situation):

I went into this post thinking, yes I can do this mod and have cabin filter. After reading the post I found out, well hell I already have it. Went outside to check and sure enough the hole is there but with no filter......there is plenty of leaves and other **** though. Now I just need to get a filter and the filter frame from a 97 -01 CRV. Good right write, especially for https://honda-tech.com/honda-civic-d...civic-2112319/

I'd like to provide an update to this thread and detail my experience performing this modification. First of all, thanks to @deschlong for the extremely detailed post and other contributors with their experiences. Much appreciated!

Details:
Evaporator box donor vehicle: 2000 Civic EX Sedan (USDM)
Cabin air filter frame donor vehicle: 1999 CR-V (USDM)
Swap performed on: 1994 Civic EX Coupe (USDM)

I chose the evaporator box from the 98-00 Civic because according to details in this thread, it would be a plug and play affair with my 1994 Civic as compared to the CR-V box, which had a two-wire thermostat vs. the Civic's three wire thermostat. This bit of information was correct, however the location of the thermostat plug on the 2000 evaporator box that I acquired is much different than the location of the thermostat plug on my 1994 Civic's box.

In the first post, deschlong linked to another build thread where the individual had a 1998 Civic EX Coupe (USDM) and a photo there shows the evaporator box equipped for a cabin filter and has the thermostat plug in the same location as the 92-95 (and likely 96-98ish) evaporator boxes (Figure 1).

Figure 1: Location of thermostat plug in correct location for 92-95 USDM Subharness, on an evaporator housing with provision for a cabin air filter.

I suspect that this evaporator unit with the thermostat plug in this location and provision for a cabin filter was a short production run in MY 1998 only. The MY 2000 evaporator box I acquired looks like the one pictured in Figure 2:

Figure 2: USDM Evaporator box from a 2000 Civic EX Sedan with provision for a cabin air filter.

SOLUTION: The solution to this problem for the 92-95 Civic chassis (USDM), is to acquire the subharness from a 98-01 Acura Integra. The evaporator box from these Integra's looks identical to this 2000 Civic evaporator box that I have. The pigtail for the thermostat is extended to reach the connector, and all of the other plugs work (blower motor, 2x chassis harness, recirc door motor, blower resistor, and climate control connector behind center console). You will need this sub harness for a factory-type install if you have an evaporator box from 99-00 Civic (or possibly some 98's) or any 98-01 Integra. Otherwise, you can simply extend the wires yourself to reach the plug. Post #43 in this thread alludes to this fact when that person used an Integra box and mentions snagging the Integra wire harness to not have to extend the wires, and post #107 details how they removed the connector for the thermostat from the housing but I could not figure out how to get mine to unclip. This is a good option if you can figure out how to unclip the connector. Note: to replace the sub-harness it may be necessary to unbolt the dashboard and lift it forward enough to remove the old harness and install the new one.

The second problem I ran into was with respect to the passenger side SRS (supplemental restraint system, aka: airbag). The airbag is held to the dash with 4 nuts, but then also bolts to 2 small L brackets that bolt to the metal bar that runs from the center console floor up behind the glove box. I was able to successfully install the passenger (R) bracket to the airbag, but the driver (L) bracket no longer fits. After wedging and turning and flipping and trying everything else I am convinced that it will no longer fit due to the shape of the top of the evaporator housing (Figure 3):

Figure 3: Comparison of evaporators between 92-95 civic and 97-01 CR-V courtesy deschlong. Notice the differences in the top contour of the cabin side face of the evaporator housing.

In Figure 3, locations A and B show two areas where the contour of the evaporator housing is different. At location A, the angle is much steeper and is lower on the left side than the CR-V evaporator. At location B, there is an obvious lower section that "steps up" to the final height of the evaporator box. I believe that it is this section that is causing me to not be able to fit the airbag mounting bracket in there. The CR-V (and Integra and Civic 98-00) evaporators do not have this recessed step-up feature. Unfortunately, the airbag for these other vehicles is different and mounts differently so the mounting hardware for those vehicles' airbag cannot be retrofitted into my Civic.

SOLUTION: I think the only choice I have is to fabricate a small L bracket to use, or modify the factory bracket by shortening it so it does not bump into the evaporator housing. The other option would be to leave this bracket off but I feel since Honda had it there from the factory that it's meant to be there and since the SRS is safety equipment I don't really want to leave parts off.

If anyone has any thoughts or has run into this issue with the airbag bracket I am curious how you solved it.

Overall, my recommendations for which evaporator to use would be the following:
1. 1998 Civic evaporator with cabin filter and thermostat plug at upper right location (must also acquire cabin filter frame)
2. 1998-2000 Civic evaporator w/cabin filter OR 1998-2001 Integra evaporator w/1998-2001 Integra subharness (must also acquire cabin filter frame)
3. 1997-2001 CR-V evaporator (comes with cabin filter frame but requires 2-wire to 3-wire thermostat swap, and may require extending the wiring)

UPDATE

Order of operations is key when re-installing the dashboard and passenger airbag after the swap to a newer evaporator housing. The left mounting bracket for the airbag that secures it to the dashboard support coming from the center console floor MUST be installed to the dashboard support PRIOR to re-installing the dashboard/passenger airbag. Otherwise the angles with the new evaporator housing don't allow you to finangle it in there because of the welded stud on one side of the bracket. I was able to unbolt the dashboard and lift it gently upward and away from the firewall which allowed me enough room to do this after the fact without having to drop the steering wheel again and/or completely remove the dashboard from the vehicle.

Bottom line: there is no interference with the passenger airbag after all, but be sure to install the passenger airbag retaining bracket prior to re-installing the airbag and/or dashboard.

Just an additional question - since you have ABS, I think these upgrades will fit my EG hatch w. ABS, but I also have SRS on pass side - I cannot remember if you do?

wxman94ej1

I have ABS and both driver and passenger air bags. Is that what you're asking?

94 Civic Si

Yes sir! Thas exactly what I am asking.

i am planning on installing AC into my 92 Cx hatchback, it is a factory non AC car. i plan on using a 94-95 civic AC system in combination with a 97-01 crv evaporator. so after reading all the comments on this post obviously most of you that have been using the crv evap are switching the original 94-95 3 wire thermostat over to it. well my question is since i have a 92 and it has a 2 wire thermostat would i be able to use the crv thermostat since it is also a 2 wire thermostat? im very curious about this and cant believe nobody else has asked this yet hahah. some insight into this would be greatly appreciated, thank you.

tony_2018

The thermostat is not permanently inside the evap, you can use your 2 wire.

So I looked in to this when I did a retrofit of an evap with cabin filter onto my 1993 Civic with 2-wire thermostat. The CR-V one has no fanciness to it other than a thermistor and two wires. The 2-wire Civic one has a little brain box on the end of it. After some consternation, I opted for the 94-95 3-wire setup instead (required some soldering, etc.). The logic to my decision is this: The CR-V one *might* work, but the only way to find out is by vacuuming, charging, then test running the system. And since the thermostat is not accessible after it is installed, it would mean I can't remove it if it *doesn't* work without evacuating the system.

Why is the CR-V one so much simpler? It could be that the thermostat technology or cooling system design evolved over that time, or else (my theory) there is logic built in to the climate control system of a CR-V that isn't there in the Civic's.

94 Civic Si

This picture is perfect!

It really helps me see what is going on.

I am just concerned that if I have a passenger side airbag, do I have to remove it to get the evap w/ cabin filter (whatever version) in there?

Next question - what is my best bet to source one of these evap units - sounds like '98-00 Civic is the preferred route?

Thanks all!

tony_2018

domt recall needing to remove the AB

94 Civic Si

Great news.

Now just need to find me one...

94 Civic Si

Found an evaporator from a 2000 Civic.

It looks like the design changed from tube-and-fin to parallel flow design from 09/93 to 1/00.

A little side-by-side comparison:

tony_2018

Can confirm that the 2000 civics got the boxes w/ cabin filter option.

edit: make sure that if you decide to replace the evap it has to be the exact same design or else the cabin filter won't fit. Most of these aftermarket parts will go '96-00' but then you'll realize too late that the filter won't fit where it needs to be.

94 Civic Si

Filter fits my man...
