you have a loss of vacuum. There is a small diameter black plastic tube from the engine compartment that feeds the climate controls. Check at back of control head, or there is a plastic connector under dash were other color tubes join to operate the other actuators of the system the black tube must have vacuum when engine is running. check under hood the black tube is spliced. separate the tube and check for vacuum The tube enters the firewall near the heater hoses.

Connection between Climate CTRL and the Radiator Fan?


the cooling fan is designed to come on when the setting is in defrost or A/C mode . the a/c compressor is set up to come on in the winter to help keep the seals flexible by running and cooling fans run to help provide air across the condenser and radiator to cool engine water and makes a/c cold in summer time use . cooling fan will cycle as it reads data from related sensors. this is a normal condition with your car

have you check to make sure the rad cooling fan is working and all the air has been purged from the cooling system, if so then the only thing left is a head gasket, cracked head, warped head. could be a block problem but this is unusual.

I changed the thermostat and the sensor and put more fluid in it took it to the store about 20 min away and it started over heating again


Find the bleed screws on the engine and bleed the coolant system of air.once the air is gone from the cooling system the engine should cool fine,also check to make sure the cooling fans are coming on when they are supposed to.

Heater not heating


If fan works, most likely low antifreeze in radiator. Also could be air in cooling system, so fill, try, let cool, fill more, try again.

Hello, you may have a blockage some where in the system or possible air in the system. Double check your coolant levels, your cooling fans make sure they are coming on. Hope this is helpful.

2002 pt cruiser overheating was told i need a new raditor and thermostat for 1 grand sounds fishy


Flush rad & change coolant & thermostat. Check operation of rad fan, & make sure it is coming on when engine reaches normal operating temperature. Be sure to bleed air out good when refilling rad/cooling system. Start engine & turn heater on when refilling & let rad fan come on & off at least 2 or 3 times before putting cap back on rad, and refill rad as needed as you do this. then fill return bottle to proper level & see what happens.
