Need A/C wiring schematics//pics
 

Ok guys, I replaced my carpets this past week and in the FD and I am almost positive I re-connected everything correctly but for some reason my a/c compressor is not clicking on when I push the button on the panel. I doubt it is the compressor clutch itself because it was working perfectly and I had it serviced right before I did the new carpet. The ECU (PFC) acknowledges the turn on of the a/c because it's raising the idle RPM and the sensor is noted as on, I just don't see the clutch engaging, therefore no cold air. Does anyone have the schematics or pictures for the a/c wiring so that I can check the connectors and the wiring to see if I missed something? Would appreciate it, thanks...

Here is part of the overall A/C wiring. What is not shown is the path "circled 99" which goes to the A/C control knob on the console. This image is from Section G of the '1994 Body Electrical Troubleshooting Manual.'

Do you have refirgerant in the system?

Pressure switch located under the battery working properly?

Does your radio and cigarete lighter work? Check the fuse for the cigarete lighter.

Thanks, I will take a look at this and see if I can't figure it out...

Yeah I just had the system recharged+new ac lines made, also the fuses are all good, the problem is some relay or switch along the way isn't engaging the compressor clutch. I can see the pulley free spinning and the clutch not engaging, it's still possible that the compressor/clutch may be bad but I doubt it as it was just working before did the new carpet, thanks for the checks though.

To eliminate the possibility of a bad compressor clutch just unplug the connector and apply 12 volts to it. Should engage instantly. also with a multimeter check for proper voltage at the same connector.

It is the forward of the two connectors on the compressor. Has one wire going to it.

Also, just because the system was just recharged and has had the lines replaced does not mean there is still refrigerant in the system. The shop could have not crimped or tightened a line properly causing a leak.
