Thanks, sorry for the slow response, I guess I did not get an email notification when you posted (just turned on "Notify me of replies":-). There is about 75 lbs of pressure (low and high side since compressor/clutch won't engage, not sure if that is enough to engage the clutch?). What I have tried so far is check signal from the TIPM at the clutch pigtail and received no power when I turned the AC on. To add to the confusion I have also attempted to put 12 volts directly to the clutch and it still did not engage, to be fair though it was hard to be sure I had a good connection at the pigtail. Next steps I am going to try is by a new pigtail (if I can find one) and plug it directly into the clutch to verify 12 volts and see if the clutch engages. I also have a new foxwell code reader on order that supposedly will allow me to send a signal to the clutch and see if it engages.
Still open to suggestions or if anyone knows if 75 lbs is enough to allow the clutch to engage that would be helpful. At this point I don't know if it is too low on freon (R134A :-), bad clutch, bad transponder (I think that is what Dodge is calling the low pressure switch, 3 wire and apparently can't be jumped?) or bad signal from TIPM. Also was not able to find a clutch relay in the TIPM, could it be somewhere else? Some seem to suggest TIPM controls clutch directly with no relay or it uses an internal relay, not sure that is the case though.
