If your PT Cruiser is running hot, and the fan is not running we’ve laid out the most common causes of this issue below. There are a few simple reasons that the fan would not be cycling on.
What happens when the a / C is turned on on a PT Cruiser?
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. This regulates the refrigerant system pressure and controls evaporator coil temperature.
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.
What to do if your AC unit won’t start?
Turn off the A/C unit and call in an HVAC technician to replace the capacitor as soon as possible. This is a quick and simple repair for a professional. If you leave the unit running, the fan motor will keep attempting and failing to start. The capacitor may also be used to keep the fan motor running properly as well as starting it.

What happens when the fan is not on on a PT Cruiser?
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.
Where is the ohm meter on a PT Cruiser?
If you have 12 volt here than check the relay for power at pins 25 on the low relay should be hot with the key on and pin 4 on the high relay should be hot with the key on. You will need a volt ohm meter for the tests.

Why is my air conditioner not working in my PT Cruiser?
The first thing you need to know is if the ac compressor is working. If you run the car and the ac compressor turns on and off (it sounds like a click noise and then the engine gets a little louder) then it is most likely a coolant problem. either a leak or simply needs to be charged.
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.
How does the PCM turn on the cooling 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. ? Engine coolant temperature ?
What to do if your air conditioner does not turn on?
If the ac compressor does not turn on, try and replace the low pressure sensor. A 5/8ths wrench is the only tool you need and when you take off the old sensor a ball valve prevents the gas from leaking out. You can check the sensor prior to buying one by shaking it. if there is no noise the sensor is bad. a good one will rattle a little.
