feel wrote:actually, did the compressor ever engage before it all leaked out or did it leak out super fast? iirc even without refrigerant, the two fans still turn on just not the compressor.


I'm not sure if anyone comments on this later in the this thread, but for what it's worth... I don't think this is true.

My AC stopped working for me and in the process of troubleshooting through, I tested the dual pressure switch with a continuity tester and the fans started up (they didn't run at all prior to that). I then found that my coolant level was low and filled it. As I was filling it, once I got enough refrigerant in the system, the fans and compressor kicked on at the same time.

Just wanted to post that for people trying to troubleshoot through their issues in the future.

Just got a complete ac system cheap from a 88 crx, installing steadily on my 91 crx si, tips- the small yellow and green plug behind climate control fit right in, my crx is a NON OPTION ac, just pop in a ac button, there is a plug behind climate control, as for the evap plug there is a hidden plug under rug, top of ecu, so far everything looks to be fitting together, ive gotten quotes from junkyard parts just for lines, condesor, compressor, evap come almost to 200. Thats not including all mounts, wiring harness, ect, So it will get pricey,

So I'm adding AC to my 89 Si, got a complete setup and almost everything is in. It's probably been answered already but I can't seem to find the plug for the wiring harness connector coming into the car through the firewall. I got the thermostat hooked up to the evaporator but I can't locate the other connector. I don't want to pull up my carpet, but can someone post a pic of where it exactly is. Once I'm done with that I can put my glove box back on, I did have to replace the 2 rubber grommets on the glove box since were dried out. Last thing left is the compressor mount followed by the Sanden compressor. Thanks in advance.

It's under the carpet and/or sound insulating pad.

You don't have to pull up much, the connector is tied to the harness close to the ecu. Just have a good look where the harness runs.
