Dodge Repair Questions? Ask a Mechanic for Answers ASAP
Hi, my nae is Tom and I'll try to help you with the AC concern on your Nitro.
Do you have an ohm meter by any chance? The code that you have is set during an overcurrent condition which can be the result of a shorted coil. I'd like to get an ohm reading of the clutch coil and go from there. Thanks
4 ohms is preferred
Ok, that's a low resistance reading which would cause too much current. Just to double check, did you ever get power to the clutch with ac turned on?
Ok, that sounds like the system is operating correctly. Fan should come on anytime AC is turned on. To cover all bases, is the system charged the correct amount?
what scan tool do you have that you read the code with?
Not sure if you can open this diagram
Is it able to read data? Specifically the ambient air temp sensor?
Does it have an actuator function. The factory tool is able to command the ac clutch on. That will tell you if the driver is working
There is no fuse for the ac clutch on this system. It uses a driver in the TIPM to power the clutch coil. If current is too high it will turn the driver off instead of a fuse blowing. Other things that will keep it from powering up are: low charge, high charge, low ambient temp reading (below 30) or bad reading, evaporator temp reading, other PCM related codes may also keep the AC from being powered.
Yes, that is also a possibility if the compressor is locked up internally the clutch coil current would spike. you should be able to turn the compressor by spinning the outside plate of the clutch. (not the pulley)
Sorry didn't understand your last post
Yes, compressor is bad if you can't turn it by hand
Yes, I'm following you. If it cuts off as soon as you plug it in then the clutch coil is shorted or the compressor is locked up. I was asking if you can physically turn the clutch plate by hand. That will tell you if the compressor is locked up because the clutch plate is directly connected to the compressor internals
