Dodge Repair Questions? Ask a Mechanic for Answers ASAP
Can I have the last 8 of your VIN to grab a wiring diagram?
I attached the wiring..
Can you remove the ac clutch relay and tell me if pins 30 and 86 have 12v? And then see if 85 has a ground when the a/c is on?
Are you sure? 87 goes to the compressor and shouldn't have anything on it... Can you double check and tell me if 86 has 12v and 85 a ground? If they do then check for 12v at the compressor when a/c is on..
Let me know
Ok so the PCM is not telling the compressor to engage.. And reasons the PCM will not engage the a/c clutch are bad pressure sensors, or low on freon.. Is it full of freon?
You could possibly burn up the clutch if it does have a very low charge. The correct way to repair this issue is to recover the freon and check for proper charge and then if monitor the pressures with a scantool.. Most of the time I find a low charge is the reason.. Also when you add freon also add UV dye because there is a leak somewhere and you need to fix it. Once you run it a while check over the entire system until you find the green stuff, then repair it..
Also if you can't find any leaks check your drain, if dye is there your evaporator is leaking and the dash will need to come out.. Another very common issue...
I hope this helps,
