Hello my name is XXXXX XXXXX I hope i can help you. Looking at everything you said it does sound like there could be a internal problem with the pcm ground control. The compressor clutch relay ground is controlled by the pcm if you can ground that relay and everything works I would start looking at the pcm. As far as you IPC cluster and the numbers you will need to replace the cluster to address that concern they do not service the IPC they are replaced as a unit. If you have any other questions please let me know and please hit ACCEPT thank you very much
So what they were jumping (they pulled the little gray item off the left front fender and jumped it with a wire to engage the compressor clutch) was that the clutch relay? If not where is that located at? I am very upset with the dealer and not sure if I want to take it back to them. Also what does it mean by flashing on the PCM? They are saying it is 80 dollars extra on top of the cost of the PCM. I am getting upset about the money I have been placing in this car.
Don looking at my info the wire going to the PCM is dark green with a white tracer the relay is located in the fuse block near the LF fender. If that relay was jumped and the compressor clutch came on I would think the PCM would be bad. As far as the 80.00 for flashing the PCM when you install a new PCM it needs the software put into it thats where the 80.00 comes from. That is a normal charge.
