I just bought a 91 CRX Si, without A/C, which is something that would be REALLY nice to have, especially driving through TX/NM/AZ in the summertime..

What would I need to install it in my car? Obviously the compressor, condensor, and evaporator, but is that it? Or does the entire HVAC system need to be changed out?

Here is a pic of everything I think i need, just wondering if i would need anything else:

do you have the ac harness also

 

Nope, that would probably be a good thing to pickup huh?

Is it a seperate harness, or is it part of the engine wiring?

 

its separate but it connect to the harness inside the cabin underneath the dash. it holds the relay for the ac fan and gives the compressor power.

 

You will also need:
- a/c pulley, pulley bracket, and belt to drive the compressor
- a/c wiring harness as said by 661rex89si above
- evaporator for underdash
- a/c switch for the HVAC controls

You should watch out for R12 vs. R134 and weigh your options. For under the dash, you will have to swap out the air pass-through "box" with the evaporator unit from the A/C. They swap right out, and you can get to it by taking out your glove box.

And when you get all those nice parts, send me that air pass-through box and the A/C button block-off!

I still have my ac button block off from when I did my ac. Also, I'd go with r-12. It gets cold a lot quicker. If you can't find r-12 send me a message and I'll tell you how.

 

I've read about something other than R134.. Maybe it was R12. You actually used less of it, and it works a lot better than R12. It's in a writeup on a/c recharging i found somewhere...

Will the A/C harness plug in to the factory under dash harness even though it never had a/c ?

Looks like it's time to start buyin someone's a/c setup

 

The A/C harness plugs into a connector near the blower motor. A/C was an option on all trim levels so this connector would be in every 4th gen Civic.

 

I plan on picking up a rebuilt compressor or whatever from autozone, and a new condensor. Im looking for lines/evaportator/wiring harness.. Thats everything, right?
