#24 of 224 Availablity of 2006 PT Cruiser A/C cycle switch ] by inlayusa

I had the same A/C problem (compressor not turning “ON”) and many owners must have as well, since this original Chrysler replacement switch is in short supply. However, I got one through Auto Zone (6-23-09) in Mulberry, FL and it should be available from them since they had to order it from their warehouse (I got it the next day) and it wasn't just one they happened to have in store stock. It did not come in Chrysler packaging but is a Santech #MT1191 (A/C Switch) Low-pressure cut-off switch M12x1.5 Chrysler. It looks exactly the same and screwed into the condenser and the plugs-in is the same including the connector lock. It seems to be just like the original A/C switch and works just fine. It cost $30 bucks and change with tax. In case you can't get it through Auto Zone here is Santech address:
 
Santech
2450 Handley Ederville Rd.
Ft. Worth, TX 76118
 
Hope this helps, InlayUSA

Thanks!! I called Santech in Fort Worth and they told me this is compatible, if not better, than the original MOPAR part (5058736AA) which is still on backorder across the country at Chrysler Dealerships. They are beginning to get their shipments, but very slowly -- and the parts they're getting in are already spoken for.
 
This Santech part (MT 1191) is available at AutoZone, XL Parts (713) 983-1100 and North Houston Starter (281) 586-7374. Good Luck to everyone!!

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?
Thanks,
Jim Welsh

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?
Thanks,
Jim Welsh

Hi.
 
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?
 
Thanks

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?
 
You're great!

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?
