Hello. Does anyone know how to bypass/troubleshoot the A/C fan switch and A/C fan relay on a 2006 Chrysler PT Cruiser? Apparently, it must be a trade secret or something, because I have searched the internet, Chrysler forums, asked for advise on the local craigslist, and nothing. Not even a whisper of advise. Oh, sure, the dealers and local repair shops will do it, only if they can replace the whole system, not troubleshoot it like I ask.

Jun 26, 2010 (3:54 pm)
After running either the heater or A/C for about 30-45 minutes and internal vent door begins to close. I can hear the fan running at different speeds I select but the volume greatly reduced. After an hour off the same thing happens again .
Are these vent doors operated by vacuum line or electrical drive?

#59 of 249 PT Cruiser 2007 AC problems
Jul 10, 2010 (11:16 am)
My ac works intermittently, but mostly it doesn't work at all. I paid to have it analyzed and was told that the compressor clutch module is not working. They said it was $600 to replace and then Chrysler may have to program it. Chrysler would not say how much that would cost. Does this make sense? I can't seem to find out anything about such a module and where it is physically located. Is it part of the compressor or clutch assy? Does anyone know? I would really appreciate any information.
Thanks in advance.
#60 of 249 What finally worked for my A/C!
Jul 11, 2010 (8:38 pm)
After three visits at two different repair shops to repair the air conditioning in my 2007 PT, here is what finally worked:
First, one shop told me that the computer module would need replacement. I did not even ask how much that would cost. Another shop told me that the entire radiator fan and cowling assembly needed replacement. The shop wanted $680 to perform the job. The reason given for the high cost was the $425 price of the original Chrysler part. I told the shop "no thanks" and I found the assembly on line (brand new) for $88. It was easy and fairly straight-forward enough to replace the assembly myself. After replacement, the A/C still did not work. There appeared to be no change in symptoms.
Next, after more on-line post readings, I paper-clipped the contacts in the Low-Pressure Switch connector that sits atop the accumulator. After starting the engine, I immediately felt ice cold air for the first time in two years. I found the switch in stock at my local Auto Zone for $29 (Santech #MT1191). It was super simple to replace. No freon vacuuming is required - just unscrew the old switch and screw in the new one. The wiring connector easily pulls off and the only tool requited to remove and replace the part is a small crescent wrench or a half-inch wrench. It is a ten-minute job. Within an hour of the paper-clip diagnosis, the problem was repaired and the A/C has been working perfectly ever since.
So, before you shell out big bucks on other "remedies", pull off that LPS connector, use a small piece of wire or paper clip and short the two contacts in the connector (do not let the jumper short out against the engine or body metal). Then, see if the A/C is working. You may want to take it for a full test drive before you decide. I did make sure that I had a full charge of freon before I tested the LPS.

Hey where did you find the part for $88.00? I took my 2007 PT to the dealership and they told me $800 to fix it!! Said to replace the Fan. And you say that might not even be the problem? My A/C works as long as I am moving but when I am stopped, it starts to blow warm air and the RPM's drop - bog down as sounds like compressor is kicking in and out? Any additional Info greatly Appreciated!!

It first started by blowing the fuse all the time, then only worked when it wanted to and now I cant get any cold air. I can feel it in the engine when it kicks on and off sometimes but only get hot air. Any ideas?

Go to www.partsgeek.com. Specify the correct year.
It was $88 for the entire fan assembly and about $9 for shipping. You CAN do it yourself; it's relatively easy. It helped that I had mini drive-up ramps and a floor creeper, but, these are not mandatory.
Remove the negative battery terminal but don't waste time removing the entire battery and battery shelf. Removing the wiring connector is a little tricky. Look at the connection in good lighting. Slide a small-bladed screwdriver between the (fan side) catch prongs and the body of the connector (the raised hump). Then pull out the (car-side) jack.
I did not open the radiator drain plug. I just shoved a short piece of plastic tubing into the radiator cap (the metal cap over the front of engine, not the plastic over-flow cap) and after it filled with fluid, I pinched the end and pulled it out to create a siphon. I drained out two beer cans worth of fluid. With the car on the ramps, this was enough to drop the fluid level below the upper radiator hose flange.
Remove the two lower fan cowling bolts then the bolt on each side. The driver's side bolt is the most problematic - having a thin arm helps. Remove the front grill by removing the four bolts on top and then unsnapping the grill by pulling each side forward until it pops out - you'll see the two snaps on each side as you pull it toward you.
Twist the two radiator retainers (black oval-shaped plastic about the size of a dollar coin) on the top of the radiator counter -clockwise and pull them off. Lift off the front portion of the rubber hood gasket and set it out of your way. Remove the upper radiator bracket bolts and the one center brace bolt. Remove the remaining two upper fan cowling bolts, tilt the radiator forward and behold! You can now pull out the entire fan assembly. Just install the new fan by reversing the process.
Easy. Budget about 90 minutes of your time.

Well, I gave up and went to the Chrysler dealer to get a diagnostic on what was wrong. First of all, my dealer charges $98 to program the module. Second of all it wasn't the module after all, it was the low preasure switch. Third of all the first garage had damaged the high-side Shrader valve and all the refrigerant was gone. I paid $247 for Chrysler to fix it and then went back to my local garage, which was, by the way, recommended on Angie's List. And raised hell with them. They apologized and refunded the $182 which they had charged for the labor the first time and threw in an oil change. I don't believe I'll take the oil change though. :>)
Thanks BThompson. Must be a lot of this going around.
