PT Cruiser Air Conditioning Questions/Problems

  • so i can just swap the plugs on the 2 relays that are on the fan shroud and if it is the low speed fan it should come on when i cut air on...Could the smoking be the fan motor?
  • If memory serves me, I believe that the relay connectors are snap-mounted to the shroud and the relays can be pulled up and off after releasing the snap catches. It is possible that fan motor coil burn-out could have caused smoke.
  • when i swap the plugs the fan should come on when i cut on air....? could i also straight wire the fan to see if it is working?
  • The point of swapping the relays is to eliminate the low-speed relay from the possible list of defects. So, if the low speed fan is inoperartive before swapping and it is operative after swapping, then the relay is the problem (assuming engine running and A/C selected). If the low speed fan is inop in both situations, then seek solution elsewhere.

    Yes, if you have a set of jumper clips, you can attempt to "hot wire" the low speed fan circuit and test operation.

    If you want to pony up the dollars, most shops will charge you around $60 to diagnose your A/C system. If one does verify that the low-speed fan is the issue, then you can proceed with DIY replacement.
  • WELL I TOOK IT TO GET CHECKED AND HAD A COUPON FOR FREE A/C CHECK AND WHEN THEY CUT THE AIR ON SPARKS SHOT OUT FROM THE FAN AND THE WENT TO RUNNING LMAO....THEY DIDNT KNOW HOW THE HIGH SPEED FAN WAS STILL WORKING BUT IT ...THEY CALLED THE DEALERSHIP AND THEY WANTED $567 FOR FAN AND THEY WANTED $180 TO PUT IT ON...SOOOOOOOOOOOOO THANK GOODNESS FOR EBAY...$108 BUCKS AND SHIPPED TODAY AND I GOT A TOOL BOX AND 2 BOYS THAT NEED TO LEARN HOW TO WORK ON STUFF,,,,THANKS FOR YOUR HELP :)
  • JUST GOT DONE PUTTING NEW FAN ON AND ITS FIXED WOOOHOOOO NOW TIME TO TRADE THAT [non-permissible content removed] IN LOL.......2008 CAR AND HAVE TO PUT NEW FAN AND CAM SENSOR.....CHRYSLER SUCKS
  • Congratulations! I know the feeling of elation that you are now feeling. It is a shame that Chrysler has not maintained the standards of quality for its suppliers that it has established for its own manufacturing. The fan assembly and the CAM sensor were designed and manufactured by third-party, lower tiered suppliers.
  • Thanks to all the posting in this forum I got the quick and inexpensive fix to my air conditioning. Per advice and very good instruction by bhtompson I now have cool air again. Just as many others complained mine went out suddenly and blew only hot air. I replaced the LPS switch which cost $30.00 and was lucky to get the last one from Auto Zone in my area. Thanks again for all the advice
  • Let me also say many thanks to the guys who posted their info in this forum...It's save us a lot of $$ and time.

    I took it to a local Meineke and they said they tested everything and freon and relays were good...they thought it was a compressor going out. Told me to take it to Dodge as we only have 46K miles on the car.

    I took a chance with the LPS as jumpering the connector would get us cool air....got the part installed this morning and took a 2 hr round trip..so far so good!

    I wouldn't have known this was a common issue had it not been for this post!! Thanks again!

    Just a FYI also that santech part seemed a bit heavier than the OEM part...hopefully this one will last the life of the car!
  • I travel out of town quite a bit so i haven't had the time to work on my a/c issue lately. Today I verified that the fan behind the radiator works, tried to put in R-134a with sealant in and still getting nothing. The old LPS is in (because there was no change with the new LPS in, and it actually blows cool at idle with the old LPS), the a'c blows semi-cool air when sitting still in park if you have your hand right up near the vent. I took the car for a high speed (65-70mph) test for about 8 miles to see if it blew cold like it used to at high speeds............nothing, still hot. It actually seems to be cooler when sitting still than moving now. It was 101 degrees out today during the test drive. So far $60 bucks in with no results.......I have a coupon for a free a/c check at a local repair shop so I guess I'll see if I can get it over there for that. I am on call 24/7 for the next 6 days so getting it there may be a problem. Any other previously unposted ideas that I can do while I have a little time today?
  • I believe the previous posts covered just about all the bases. It sounds as though you may have a problem with your high-speed radiator fan but I would expect to see the engine run hot if that is the case. When you charged up the Freon, did you do so with a gage? With the gage attached and A/C on, you should see the change in pressure as the compressor cycles. An over-charge might cause the high-pressure cut-out switch to trip at higher RPM. If all else fails, use the free coupon for a diagnosis and then return to the on-line posts for the DIY repair.

    Good luck.
  • I bought a 2006 base PT cruiser in '08. Since I bought the car, I have had a/c issues and overheating issues. Here's how my story goes. Within the last year, I have replaced about 3 fans, one a/c cut off switch and other things I can't even remember. Nevertheless I have taken it time and time again to have the same problem occuring. Let say my car comes out of the autoshop with the a brand new fan and the whole nine yards, 3-6 months later, I'm stopped at a red light and all the sudden my car starts shaking, my fan turns off, and BAM!!!!!!!!! my car fricken overheats on me. It never fails, I fix my car and then it messes up. Can someone please help me?!?!?!?!?!? What does my a/c have anything to do with the car overheating????????????
  • Oh oh oh!!!! not to mention now I have a dying cat under my hood when I start the effin car. Please I can't anymore. I am in desperate, desperate need for some experienced opinions here.
  • Hi Sad Girl:

    It is more likely that your overheating problem is the cause of your A/C problems.
    In order to attempt troubleshooting via the form, we will need more information.

    1. By fan replacement, I assume you mean the radiator fan/cowling assembly(?)
    2. By A/C cut-off switch, do you mean the Low Pressure Switch (LPS) or the High-Pressure Cut-off?
    3. What other parts/compnents have been replaced?

    It is possible that the root cause is electrical related and not component/part related. If that is the case, perhaps not all three fans were bad. The Powertrain Control Module (PCM) activates the high and low speed radiator fan relays by grounding one side of the relays. Faulty wiring or a PCM issue can prevent this. Does the ar ever travel through coastal salt water?

    Are you having this work performed by a private mechanic(s) or a Chysler dealer?

    The more information that you can provide, the easier it will be to determine the root cause.
  • Well, I'm back next step is to replace the fan, the new LPS switch is no longer blowing cool air and the freon is good. Uggg Why can't we raise enough H*LL to get Chrysler to fix the problems.
  • Before you let a shop take your money, do these two checks first (assuming that you are correct and your Freon is as it should be):

    1. With the radiator cool (in the morning or before driving for the first time of the day) and the PT in Park and at idle, turn on the A/C on low blower speed. Use a flashlight to see if the radiator fan is running. It should always run if the A/C is on. If the fan is not running (on Low Speed) it may be defective IF the fuses are good.

    2. If the radiator fan is running then return to the LPS paperclip test (see my previous posts). It only takes two minutes to check. The OEM LPS devices seem to be problematic, the replacement switches available from Auto Zone are reported to be better.

    If shorting out the contacts in the LPS connector (connector and NOT switch)produces cool air, then you have found the source of your problem (perhaps for the second time).

    Hope this helps.
  • Another person with an A/C problem... Less than two weeks after I purchased my 2006 PT Cruiser the a/c stopped working after driving about 20 miles. I brought it to the dealer and they said the a/c was actually freezing, that ice build up on the a/c and the ice was blocking the air from coming through the vents. They told me to turn off thew a/c so the ice would melt then it would work again. They then said it would cost $690 to fix it, replace the part that was broken. I reported them to consumer affairs for this and other issues because I purchased the car less than two weeks before all of the problems... Any suggestions? Why doesn't Chrysler recall the car for this? It seems many people have a/c problems.

    And has anyone ever heard that you cannot use burned CD's int he CD player? The dealer told me to only use store bought CD's when I told them the CD player was not working.

    And finally, Only 39,000 miles and the clutch went. The person before me obviously could not drive a stick shift... Or is this a known problem? :mad:
  • Swing, That was my first sign before my AC went out completely. But it was the low pressure control. Which should not be that expensive. And has been discussed on here over the past month or so.

    Good luck Karen.

  • Hi all my AC uniton my 2005 PT convertible, just statred blowing warm air,but not all the time,i noticed a puff of what i thought was smoke come out from under the hood.but,it turned out to be a blow back or preasure release i could smell freeon/refrigerent.This is a new problem.The engine starts ideling very rough when this happens.Any ideas ?

  • It's probably the low-speed radiator fan. Review previous forum posts for troubleshooting/replacement instructions.
