Who replaced the compressor?
What was the manufacturer's name of the compressor?
Was the A/C system professionally charged after replacing the compressor?
Were the codes cleared after above?
Please read PDF.

I replaced the compressor and the condenser. The auto shop down the road flushed and pressurized the system. No leaks.
The codes have been cleared multiple times, no change.

With the eng. running, check fuses 16, 43 & 44 in the eng. compartment and fuse #4 in the right kick panel.
Did you reinstall the AAC and radio etc.?

I have reinstalled the AAC, but not the radio. I left it out because the right hand lever wouldn't release properly and I almost cracked the dash just trying to pry it out the first time. plus with it out, it makes access to the AAC easier.
I was planning on checking the AAC again to make sure it hasn't blown during this whole process.
All of those fuses read 12v from both ends of the fuse with the car running and the AC on full auto.

OK, remove the AAC but leave everything connected. Locate conn. #A which should be the first one on the left facing the back.
Start the eng. and select AC. Test wire #1 PINK & wire #2 RED for 12v.

With these readings it can only mean that there is not enough refrigerant in the system or you have installed the wrong/cheap compressor. Of course you chose the cheapest one, UAC, but you should have chosen the Denso which is original equipment.
And there is no call for the replacement of the condenser because the compressor was replaced.

ok, I'll double check the refridgerant.
The compressor upsets me though. If it is a POS and doesn't work out of the box, it will be a hassle.
thanks for jumping through all the hoops on this one.
I'll update this thread when I have more information or changes.
