#184 of 226 Re: 2006 PT Cruiser ac problems [pcgranny]
May 30, 2012 (3:45 am)
I just fixed my car that was doing this (AC would quit at a stoplight). Mine required replacing the radiator fan assembly ($100 on Amazon.com), as swapping relays would not fix it. Again due to the high speed fan failing and the AC system overpressurizing at a light with higher heat/less air moving.
Changing is pretty easy (an hour or two), just have to tilt the radiator forward, instructions can be found by googling it. Just be careful draining the radiator as I broke the petcock o-ring and had a challenge finding the right size to replace it.

I'm going to TRY to keep this as short as possible. Just had the compressor, evaporator & dry replaced on my 2003 PT Cruiser/total cost $1,000. Air didn't blow cold enough from day one, a week later they replaced the compressor again (under warranty), air still not cold & then told me I needed a new condenser for an additional $400. FYI... the original compressor was leaking & intact (i.e. it did NOT "blow up"). A relative checked it over and said no way I needed a condenser & he "thought" there might be a vacuum problem. Took it to my regular mechanic who concurred. The "door" was stuck and only allowing outside air to come. He also found the Freon to be low (said the other shop may have done this on purpose) & once those two issues were resolved the air was ICE COLD. Also checked for leaks & found none. I have it in writing the condenser is FINE. The shop that replaced the system voided my (2 yr) warranty because I refused to allow them to put it in. They said a “high pressure reading on one side” indicated the condenser is clogged. Today (a week later) all of a sudden no more ice cold air (it IS working to some degree). ??? I am at a total loss insofar as WHO to trust, no more $$ and don't know what to do! BTW... I'm in FLORIDA (enough said). Can anyone here help?? Thank you in advance!

I have a 2002 Pt,the air stop working only blow hot air , so far i change the low pressure switch, i install 134a freon, the gage go between 40psi to 50psi, i install the pressure gage and when the compressor is not kick in is 40 to 50psi the compressor kick for less of 20 second and the pressure drop to zero, kick off and go back up, but the real problem is the return line from the coil inside the pt frost cool but the low side is hot. Anybody got any idea how to fix the problem? thank for the help

Even though you replaced the LPS, are you sure the low-speed fan is operating?

First, is the Low-Speed radiator fan cycling when the A/C is engaged?

How do I tell if the fan is engaged?? If it helps, I DID have to have the cooling fan replaced a few years ago (this car has been a nightmare in general).

The radiator fan should cycle at low speed anytime the A/C (or defrost) is engaged - assuming that the engine is not already so hot that the high-speed relay is engaging the radiator fan in high speed.

Thank you for replying. Assuming the fan checks out ok... do you feel this situation warrants a new condenser after all?? I have two (certified) mechanics each telling me something entirely different!!

I check the fan and is not running on low speed actually some one got it direct on the high speed (with straight wire on the yellow wire) i dont know how really work so excuse me for this question. The slow speed suppose to run when you turn you ac on to keep the tempesure of the engine cool? so if the fan is running all the time at high speed what is the different? Thank for all you help
