Is there a problem with the Chrysler PT Cruiser cooling fan?
Is there a problem with the Chrysler PT Cruiser cooling fan?
The car began repeatedly overheating requiring ac to be turned off. The cooling fan has ceased working and an entire assemble needed to be purchased. In discussing this with two separate garages, they indicated this was a common problem that they see frequently and should have been a subject of recall.
How does the PCM turn on the radiator fan?
The PCM turns on the fan through either the high or low speed fan relay. The PCM provides a ground to the relay’s control circuit. To control radiator fan operation, the PCM looks at inputs from:? Engine coolant temperature? A/C pressure transducer (turbo only)? Ambient temperature? Vehicle speed?
Why does my Chrysler PT Cruiser stall when stopped?
The contact stated that if the air conditioner was activated, the engine would idle low when the vehicle was stopped in traffic, a stop sign, or red light. The vehicle would almost stall before resuming normal operation. When stopped, warm or hot air would blow through the vents.
Why is the radiator fan not working on my PT Cruiser?
Without the coolant hitting the sensor, the temp reading will be significantly lower than the actual engine temp. Your PT Cruiser’s radiator fan will not kick on. If you do have low coolant, don’t fill it up until the engine has cooled off.
What should I do about my Chrysler cooling fan?

What happens when you fill up the radiator fan?
If you do have low coolant, don’t fill it up until the engine has cooled off. Adding coolant to a radiator dry enough not to trigger the engine temp sensor can cause problems from drastic temperature change. Let it cool down first.

Why is my cooling fan not coming on?
Cooling fan not coming on- replaced a bunch of times, and every time it works for a while then will die… Fan works when I test it out with a ground and a positive wire from the battery. Only overheats when no airflow over the radiator.
What’s the normal air pressure on a PT Cruiser?
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.
How does the a / C compressor clutch work on a PT Cruiser?
The A/C low pressure switch is electrically connected in series with the A/C-heater control mode switch and the A/C high pressure switch, between ground and the powertrain control module (PCM). The A/C low pressure switch contact opens or closes the path the ground, signaling the PCM to turn the A/C compressor clutch on and off.
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.
Is there a problem with my PT Cruiser?
See all problems of the 2001 Chrysler Pt Cruiser . The contact owns a 2002 Chrysler Pt Cruiser. The contact stated that the vehicle overheated constantly and the air conditioning was blowing hot air. The contact waited for the temperature on the vehicle to cool off.
When did my PT Cruiser start to smoke?
On sept. 20, 2010, I was returning home in my 2006 Chrysler Pt Cruiser convertible when I noticed a “burning” odor inside the car and saw a lot of smoke coming from the passenger side of the engine. My husband and I had the car towed to a dealership to see what happened and get the necessary repair.
How to troubleshoot a Chrysler PT Cruiser cooling fan?
Upon inspection, we determine the cause of this condition is something often overlooked, a cooling fan problem. We tackle this cooling fan using basic electrical troubleshooting methods, and learn a lot about the system while doing it. Some testing techniques I used… I hope you guys enjoy!!! Loading…
Why does my 2006 PT Cruiser overheat?
2006 pt cruiser 2.4 turbo ho put on fail proof thermostat a month or two . Don’t not overheat on 20 mile drive but does on a longer trip. Radiator is full just notice coolant tank may be leaking could that be the only problem or something else? Cooling fan is working also. Is this a good question?
What should I do about my PT Cruiser battery?
As for the battery dilemma, you need only insure that you have a well charged unit (recent is always good) with very secure CONNECTIONS!
How can I tell if my PT Cruiser has an A / C compressor?
Open the hood of your PT Cruiser and inspect the belt on the A/C pump. If the belt is broken, obviously this will prevent the compressor from working. However, the belt is a drive belt, so check the entire drive belt on the front of the engine for any signs of wear or deterioration.
Why is my air conditioning not working in my PT Cruiser?
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?
Why does my air conditioner have excessive low side pressure?
Since the fan is not on, the freon actually seems to boil in the condenser causing the compressor to cycle and excessive low side pressure because of the condenser not being cooled down Your right about that. than there is two relay in the outside fuse box the control high and low fans. and two relay for this system.
