When I turn the switch to Max A/C or A/C the compressor will not engage. After a little while it might engage or it still may not. I have checked the R-134a pressure and they are in the normal range according to the manual. Any suggestions on what the problem could be? Thanks!!
Here is the wiring diagram (in 2 parts). If you need an explanation on them, post back. In the second diagram, it shows the pressure swittches. they connect ground to the PCM to operate the relay for the compressor. They ahve been known to cause problems. as well as other items.
If you checked the pressure and it shows normal range w/o the compressor running then you are low. What pressure reading are you seeing?
