Okay, this is on a 03 CL. I replaced the compressor about a month ago and it started making noise. After diagnosing the issue I found that it was compressor. So I got a new one under the warranty.

So I replaced the compressor and condensor yesterday and once I got everything back together and vac the system out everything looked good. I then started the car and turned the AC on to charge the system. I noticed that the compressor did not engage nor the condensor fan OR radiator fan would start.

I have checked over and over all the connection and can't seem to find anything missing. I even tried hooking the old compressor back up to see if it would engage and it wouldn't. So I am at a loss at what the issue could be.

Any thoughts would be greatly appreicated.

Also isn't there a way to do a diagnositic from the control unit to see a trouble code? I tryed the "holding down off" and hit the "recirc" button 5 times within 10 secs. and that doesn't seem to work.

Please help!

 

if all plugs and wires are connected properly, i would check the fuses next. definitely sounds electrical.

 

Did you actually start charging the system? You need to give some pressure for a pressure switch otherwise compressor wont start

 

Ah ha, after doing some googling, you are correct, it was the pressure switch holding everything out. I just jumpered it for a short period of time until I had enough pressure on the low side to meet the demand.

Thanks for the help.
