It is a circuit, so that could be a possibility. check the wires to see if it is grounding out, wires touching metal

SOURCE: ac was working fine the

Check the low switch by the dryer or accumulator, its a long narrow cannister,

it will have a pressure switch attached to it or near it. put your, ac on high,

pull the molex off the switch and jump the molex with a wire or paperclip,

if the compressor comes on and the ac starts to cool, you will just need

to replace the low pressure switch, if the clutch does not come on,

check the low switch molex to see if there is 12vlts there. good luck!

Which fuse is for the fuel pump?


All of the electrical current distributed throughout this vehicle is directed through the standard equipment Totally Integrated Power Module (TIPM). The molded plastic TIPM housing is located in the left front corner of the engine compartment, just behind the air cleaner housing and the battery. The TIPM housing has a molded plastic cover. The TIPM cover is easily removed for service access and has a convenient fuse and relay layout label affixed to the inside surface of the cover to ensure proper component identification.

The TIPM housing is secured to the left inner fender well an indexing pin and one *****. All of the TIPM outputs are through the integral engine compartment wire harness.

2007 Dodge 2500 5.9 diesel. When you turn on AC you can see clutch try and engauge and after 3-4 tries it stops. No AC. If drive around for a while AC starts to work after engine heats up?

Working same problem today on my 2006 Mega Cab Diesel. 2 possibilities. Either the compressor clutch coil is going bad ( totally integrated power module tries to engage it a couple of times, senses the coil resistance is wrong and shuts down) or the TIPM (Total Integrated Power Module) is bad. I'm leaning toward clutch on compressor but still have testing to do to isolate. Could be both, but I doubt it. New TIPM is about $900 it appears from what I read. New compressor is cheaper. May be able to replace just the clutch coil for even less but reading mixed results. Good luck.

I have a 2001 pt cruiser and recently i had to replace the water pump. now my heat and ac fan will not work. no noise or anything.

See if the compressor clutch engages, check that the inner parts of the belt pulley turns together with the outer part/ belt. If not the clutch circuit or the pressure sensor connector on the pressure tube may have been disconnected during the change of the water pump. Or maybe you just run out of refridgerant? Low pressure --> the compressor runs constantly but no or little cooling effect.

My 2006 PT Cruiser rear wiper does not work. The motor tests okay. The rear washer works. The wiper is not getting power.

It may be related to TSB 08-027-06 which calls for a TIPM software update. The TIPM module is part of what controls the rear wiper. You will be stuck going to a dealer to have the software update performed though.

Car overheating and ac is hot and have 0645 code

There is an electrically driven clutch on the front of the air conditioning compressor which engages when air conditioning is required The AC compressor has a fan belt driven wheel on the front of it. The belt turns this wheel all the time. When the a/c is off this wheel spins freely. When a/c is required the electrically driven clutch engages this spinning wheel to supply drive to the a/c compressor shaft. The 0645 code concerns a fault with this clutch.

When I turn on the AC the power sterring goes out and the belts make a screcching noise?

Sounds like the AC compressor is locked and won't turn when the AC clutch is activated. Suggest professional help for this problem (or don't use the AC at all!). Good luck!
