I'm wondering if anybody can help me with the problem I'm having with my A/C. I turned on my A/C and the compressor is not coming on. I first checked the compressor harness to see if anything got tugged on or what, and the harness is fine. Checked all the fuses and relay, and made sure the compressor isnt frozen. After that, I wanted to see if I could hot wire the relay, and it came on when I hot wired it, but not when a relay is in. So, I checked the pressure switch and it isnt getting power to it. So now, I'm kinda stuck with where to look now. I was thinking to check the control head, but everything on the control head is working, including the light the indicated the A/C switch is working. Since I just swapped to an OBD1 ecu, could this be a problem in the ecu? Any help is appreciated. Thanks
