#26 of 249 Air conditioning problems
Jul 05, 2009 (3:05 pm)
Same problems as described by everyone else in regards to the air conditioning. I have a 2006 PT Cruiser, 45K miles. Air conditioning started acting up. Compressor cycling rapidly, ‘bucking’ at a stop light, blowing warm/hot air at stop. Going around a corner sometimes the a/c would ‘catch’ and blow cold air. Noticed sometimes when turning on a/c, I would hear a sound like a flapper valve slamming shut. Noticed what appeared to be a cloud of steam or vapor coming from under the left headlight area, also noticed moisture vapors coming in through the vents. Took it to the local Jiffy lube to have the R134 checked. They told me that the compressor was not cycling, but there was no leaks.
Long story short, all I get now is hot air coming through the vents. I have verified that the cooling fan does kick in. I tried disconnecting/ bypassing the A/C Clutch Cycling Switch to see if that would make any difference with no luck. Is there any other switch/sensor or relay I can bypass to see if the compressor will cycle?

We finally got our air conditioning fixed. After they replaced a lot of things (and it still didn't work) they discovered that the hoses to the air conditioner were getting crimped every time we turned the wheel and the freon was leaking out. They replaced all the hoses and now we haven't had any problems.

I do not think that is the problem on my Cruiser. I did notice that there was a sending unit/sensor on the compressor itself. The only way I can see to access this sender is from undernieth unless you have very long, small hands and arms, then you can do it from the top. What would happen if I bypassed this sender, and is this the same sending unit as the santech?

I have an 07 PT and this just started happening to me in the past few weeks. I am the original owner and so (supposedly) still have that lifetime warranty and have around 60,000 miles on the car. I took it to a local mechanic and he said that it was my fan not kicking on (didn't say which one) and that it should be under warranty still and that the dealership would have to fix it.
I know very little about cars and don't want to take it to the dealership to get royally screwed over. Can ppl advise me what I need to ask/talk to them about or what actions to take?

You can now buy the fan at ORIELLY AUTO PARTS for around a hundred dollars. It is the fan moter only(that is all you need) the dealer wants to sell you the assemble. You can change it yourself in about an hour, it is a pretty simple job. You can drive the car at hiway speeds and it will be fine. If you are in town or in traffic it will start to overheat. While at hiway speed the car gets enough air flow to keep from overheating. If you have any questions i will be glad to try and answer them for you.

Thank you so much!
Would the fan be something that would be covered under the lifetime-power trane warranty? I am the original owner and if it's something covered under warranty I'll let them fix it?

i wanted to thank you for this post! my air conditioner is fixed now, just in time for the first really hot week in the northeast this summer.
a note to other 2007 pt cruiser owners who can't get the original low pressure switch from chrysler -- the santech part (MT 1191) is on back order now too but MT 0205 in conjunction with MT0135 will work too. I got this info direct from santech.

can you tell me when you changed this part did you have to drain the a/c or are you able to just replace it?

Same problem here. Base model '06 PT w/manual transmission, 52.7K miles. Just started happening maybe 10 days - 2 weeks ago (a/c blowing warm at slower speeds, one incident of smoke expelling from left side following short hiss, terrible idle w/ a/c on, etc.). Firestone quoted me $1251.00 to fix! They said high end pressure 500psi. Took car to AAA Auto Care. It's there right now. Awaiting word tomorrow, but would very much like to repair for MUCH less. I'm not mechanical, however, so not sure what to expect re: making a repair myself or via a mechanic friend. Already out time and $$ for multi-day car rental, etc. I will also call Chrysler and at least let them know that I am another customer with this problem. I'm sure grateful for all the info here and to know I'm not alone.
#35 of 249 Need A/C High Pressure Hose - 2002
Aug 13, 2009 (8:28 am)
My 2002 Cruiser has a hole in the high pressure hose connecting the condenser and compressor. My repairman's efforts to secure a replacement part have proved fruitless; his supplier can only find four in the country and those dealers won't sell them. Does anyone have any good leads on where I can look for this hose? Thanks!
