Has anyone successfully (re)installed the heater and AC components into an EF?
a decade ago i had removed EVERYTHING from the CRX and now i am older and need all of it back. pointers, suggestions, opinions. etc. are all welcome.

 

I installed AC in my EF a few months back. Get ALL the parts back. EVERYTHING!!! Go to a pick a part and you will get familiar where all things go. Take your time. It's actually pretty easy. Use the diagrams from the manual or Majesric Honda to help too.

 

i've a spare CRX that i will scavenge the parts from, had you had any problems getting parts that NEEDED to be replaced (dryer, etc.)? where do you get the sealing foam for the ducting?

 

dryers are usually 10-20 plus shipping on ebay.
as far as the foam sealant i would look into some weatherstripping tape.

 

sounds great, thank you

 

Just earlier this year I completely re-did my ENTIRE A/C system complete with R12 with all new parts except the actual hard lines. Cost me right around a grand in parts alone, but proper working AC in an EF is heavenly. I'm glad I did it.

One thing I can't stress enough is to absolutely replace the dual pressure switch and the evaporator thermostat. You can still buy these new from Honda but supplies are low. It's only about $130 for these parts but you'll thank yourself when your newly rebuilt system actually cycles properly and you don't have to rip it apart again when you find out either the dual pressure switch or evaporator thermostat are failing. $130 now can save you a ton of headaches down the line, plus the peace of mind.

I applaud your effort. Personally, even back in my extreme riceboy days, I've NEVER understood the ricer obsession with ripping out creature comforts just to make your 15 second car a smidge faster. Maybe that's the Texan in me, though. Gotta have AC here.

 

i can see my engine through the holes in the dash and the firewall! that all will be remedied.
is the switch and the thermostat located in the heater core assembly?

 

The dual pressure switch is on the hard line under the battery box. The evaporator thermostat mounts to the evaporator box begind the glove box
