Thanks

Is there anything else to check you can think of. We hooked up a friends high end snap on scanner but it wouldnt tell me what I thought it would. It did tell me when turning the AC switch on the dash on/off was working. It also said the relay when commanded the relay was being commanded. This what I know

compressor works fine when jumped
no power at plug for compressor
fuses fine
the temp sensor on evap box I jumped the two green wires still didnt work
i bought a new pressure transduce sensor out by firewall still didnt work

around same time my blower would only work on level 4(not sure when ac quit though)I replace the resistor and it works fine

Re: AC Compressor Not Kicking On

Well, there is another inline connector that has a history of problems with burned pins. C201 is behind the right kick panel. There is a picture of it in Post #24 above. The ground wires and power wires for the HVAC system pass through that connector, as well as the signal from the evap temp sensor going to the BCM.

Re: AC Compressor Not Kicking On

Update
After checking both connectors and they were ok, I didnt know what else to check. So I took it to a friends shop. His guy found the problem thankfully. I have not seen it yet but they said that a wire harness down by engine block/tranny area that was either chewed by a critter or rubbed on metal. They say it works fine now. Thanks to eveyone who helped out.

Re: AC Compressor Not Kicking On

Can't beat "hands on" troubleshooting. Glad you got it fixed.

Re: AC Compressor Not Kicking On

Make sure the thin green wire hasn't snapped loose from the connector. I had to do so much shaking and squeezing on the C203 connector pictured above (usually while driving) that the wire snapped off from the connector. It only has like 6 strands of copper in it, so it won't take much stress. Just cut all the wires from the connector, match them up accordingly and butt-connect them together with bullet or spade connectors. Then zip-tie them all neatly to that steel bar behind the glovebox to keep them from dangling in the floorboard. My wife hits them every time.
