Hey guys so I'm in the process of installing a/c in my car and have a couple questions. First of all, I noticed that my headlight wire harness does not have the plugs that plug in the a/c components. Do I need to buy another headlight wire harness from a car equipped with a/c ? Also I was doing some research and read that I may also need to buy a box (evaporator ?) that goes under the dash, but I also read that some people mentioned that all cars after a certain year came with it from the factory. Would I also need to buy this as well ? If anyone knowledgeable knows of this information, your help will be greatly appreciated .

Thanks

 

u need a ac harness and also check under the passenger glove box to see if u have a big black box.thats your evaporator.or u can see it from engine bay area.on the fire wall behind battery..see if there is a shiny oval shape of aluminum metal with 4 holes on it (2 small holes for bolts to go in and 2 bigger holes for ac piple to connect to) ,with a weather seal around it.thats your evaporator.

Wouldn't checking for an evaporator in a non AC-equipped car be like checking for a turbo charger on a skateboard?

OK, if your car is a factory AC delete car, the following will help. To verify it's a factory AC delete car, you should notice an oval shaped rubber plug behind the battery tray with no aluminum showing.

You need the following to put AC in:

1. Evaporator with both firewall mounted grommets and drain hose. This goes in through the glove box hole. If your car is a factory AC delete car, this will just be an empty "box" that lets air through.

2. AC "button". This is just the plastic part as the switch and light are already on your climate controls after you pull the plastic "plug" off.

3. Condensor fan harness. This plugs in on the driver side of the radiator support. Factory AC delete cars have a white/clear plastic cap that goes over the part of the harness in the factory wiring. It plugs in there.

4. Condensor, condensor fan, hard lines, soft lines, compressor, compressor tensioner (factory driver torque mount already has the holes tapped for AC...) filter dryer (goes by windshield washer bottle.)

5. AC compressor relay, condensor fan relay, fuse for AC.

To put it on, pull glove box and support brace that goes across the bottom of the opening. Look at your evaporator. Bolts are in the same place on the delete box. Pull delete box out then put rubber grommet in firewall for AC hard lines. Knock out the rubber plug where the AC drain goes and install the "ring" grommet. Now, put the evaporator in and bolt it down. Extra plug should be there right by it. Plug it in. Typically, Hondas have a blue band of tape around connectors and wiring where an option not yet installed is.

Bolt AC compressor on and install tensioner and belt.

Now, install the hard lines and filter dryer.

Install condensor with fan assembly and wiring harness already attached. Extra plug goes to the pressure sensor on filter/dryer. Plug harness in to factory harness. It's between the condensor and driver headlight. Hook up the hard line that goes from the condensor to the filter dryer during this process.

Plug AC compressor in. It plugs in at the bottom of the condensor fan assembly.

Install the 2 hoses that go to the compressor. One will attach to the condensor and the other attaches to the large hard line.

Install relays and fuses.

Install vacuum pump and pull vacuum on system for 20 minutes AT LEAST. Turn off gauges and turn off pump. Verify system is holding vacuum. If it is, charge it up and enjoy AC!!

 

Finally an answer ! Thanks a lot Ryan ! Very helpful information !

 

Just ran across this old thread. Are there any AC kits that can be purchased for a 1997 CX hatch?

 

I wouldn't say there are kits available, but rather aftermarket and OEM parts available. My 98 Civic HB that I bought in Germany did't have AC, but when I finally moved back to America and went west to Arizona, the first thing I did was go to Honda and buy the whole complete AC system for my car.

You can save alot of money by looking for parts on eBay, the local junkyards, and people parting out cars. I would invest in a new harnesses, AC pressure switch, and a new receiver dryer if you go the used parts route.

 

No kits, but A/C is aplenty in junkyards.
Use this in the reverse order to direct your junkyard uninstall, and install into your own ride: https://web.archive.org/web/20101202.../17561_01.html
Also this DIY will be a near-identical install to yours: https://honda-tech.com/forums/honda-...ol-eg-2920543/

Read about retrofitting a cabin filter. Great upgrade and should be done during A/C install.

 

Thank you so much!
