#1 of 249 2006 PT Cruiser ac problems
Oct 12, 2007 (1:53 pm)
hi my wife has a 2006 2.4 touring edition with 36.6 k miles on it and the AC knocked off today...i cant find any relays or anything in the fuse box that seem to have anything to do with the HVAC system except for a single 10amp fuse that is fine...fyi when i have the hood up and the ac on i dont even hear the compressor cutting in and out...i dont think that it is low on coolant because in my previous vehicle experience they would gradually become less and less effective until they quit cooling because of coolant loss....any help would be appreciated thanks guys and gals
#2 of 249 recent problems with PT
Jan 05, 2008 (1:38 pm)
Hi all, I have a 2005 PT Cruiser that has recently started giving me some problems. I notice when I am sitting at a light and my AC is on the car jerks. It is so bad that I have to turn off the AC. I noticed this AM that the lights even flicker as it is jerking. I took it into the shop and they did a complete system check and said they couldn't find where the problem was. I am still under warranty on this. Does anyone have any ideas?
I have 49,000 miles on it.
#3 of 249 cooling fan problem
May 22, 2008 (6:51 pm)
I have a 04 PT Cruiser 2.4L Non Turbo. When waiting for a traffic light the A/C vents start blowing warm and the compressor cycles very fast. (driving along is fine, ice cold air) I noticed the electric fan was not working. At home in the driveway it works perfect. It idles with the fan running and ice cold air out of the vents all day.
Anyone else have this problem?

I am not an expert but it seems that your problem may involve a sensor that controls the engine's idling. The A/C adds an extra load on the engine and there's a sensor that adjusts the idle for the additional load. This may be a good place to start to find the answer to the problem. Good luck.

#6 of 249 2005 PT Cruiser A/C problems

My PT cruiser (2005 touring edition w/ 2.4L engine) is having the same problems as all the others in this forum. The compressor cycles erratically causing the engine rpm to fluctuate and jerk. What I noticed today when connecting my gauges to the system was that the reason why the compressor is cycling on and off is because the high side pressure is rising above 400psi. When it reaches approximately 450 psi, the high side pressure switch cycles the compressor off for safety reasons. The normal operating pressure for the high side is about 150 - 200 psi. Not sure what is causing the pressure to rise so high, but it appears that there may be a blockage in the system restricting the refrigerant flow.

When your high side pressure spikes to 400psi or higher, that could mean that you might have a bad radiator fan motor,or a bad fan relay. Also your engine may be overheating. on a 95 degree the high side pressure should be approxmately 275-300psi.

In response to 93taurus's comment, I already checked the operation of the radiator fan motor and relay and they both seem to work fine. As for the high side pressure, it spikes above 400 psi within 4 mins of starting the vehicle up from a cold start and with the a/c on high.

The PT Cruiser has a two speed cooling fan. If the A/C pressure is climbing to 450 pounds while sitting still it's most likely going to be either the high speed fan relay (most likely) or a bad cooling fan.(least likely) Without the extra air flow through the condenser from the high speed circuit the pressure will spike until the high pressure cut out switch opens.
#10 of 249 PT Cruiser Fan Module
May 27, 2009 (6:41 pm)
I started to experience the same symptoms as everyone else, stopping in traffic and the A/C starts to pour warm air out of the vents. I had the dealership where i purchased it look at it thinking it needed recharged. Instead the service person came and told me it would be close to $700 to fix the problem, i was informed that the FAN MODULE was bad. I took it to another Chrysler dealer and was told the same thing. I couldn't afford to have it replace so i opted to keep driving it as long as it didn't over heat. My daughter purchased an 07(mine is an 06) 2 days after i purchased mine at the same dealership. she called me 2 weeks ago and asked me what problems i was having and she now has the same problems as i. My future son in law also purchased a used PT Cruiser last yr and he is having the SAME problems, the local Chrysler Dealer told him close to $600 to have it repaired. I'm inclined to think that these fan modules aren't made to last more than about 40,000 miles and then give out. Isn't it amazing that you can' t find them anyplace but the DEALER, unless you can be lucky enough to find one in a salvage yard.
Anyone else having problems please contact me here. I'd like to see how many of us are having the same problems.
