Unless the car is overheating you probably just have a bad temperature sensor probably located on the intake manifold....

SOURCE: 95 grand am radiator fan only runs with AC on

Cooling Fan Temp Sensor is the First thing You Check (with what you have described) Cooling Fan Should ALways come On When The A/C is turned On as A/C Adds A Load to Engine, If Temp Sensor is Faulty it Will Not Give GROUND Signal to ECM >For COOLING FAN >RELAY to Give ground and turn ON The Fan.
There ARE 2 temp Sensors that Serve Different Purposes 1 is for Dash READING GAGE & Or TEMP LIGHT the Other is For ECM or Fan Relay (SAME Thing) you Said>""can disconnect the sensor and fan continues to run" < This Leads me to think you Changed the Wrong One. Not Questioning your Skills Just Here to Help.
TEMP SENSOR FOR 3.1L V6 is Located upper RH rear of engine compartment, near exhaust system. Temp SENSOR for 2.3L Engine is Located in LH rear of engine compartment.
I Hope this Helps Lead you to a NON-OVERHEATING Pontiac.
Good Luck and Have A Great Evening. rejakwilson

take the cap off of the radiator (whil engine is cold) start and run the vehicle. keep runnig 30mins after the vehicle is hot keeping notice of the rad fluid level.
keeping the cap off will prevent the pressure build up that woiuld keep the air in the system, keep adding water or antifreeze as the level goes down. this may take an hour or so.
also with the cap off, you will be able to see if your water pump is operating correctly. you will visibly be able to see movement in the rad when the pum is engaged.

What does the a/c temp sensor look like for a 2002 chevy cavalier?


There is no A/C temperature sensor , there is an engine coolant temperature sensor . What kind of problem are you having ? The only sensor directly connected to the A/C system is a refrigerant pressure sensor . Your A/C not working , no cooling fan operation ?

The location of a 2002 chevy cavalier cooling fan sensor


The cooling fan is controlled by the PCM - powertrain control module through a relay ! There is no cooling fan sensor , there is a coolant temperature sensor ! This coolant temperature sensor is an input to the engine computer , if there were a problem wit the sensor the check engine light would be on .
Cooling Fan Control
The engine cooling fan system consists of one cooling fan and one relay. The relay is powered by the battery positive voltage circuit and controlled by a switched ground from the powertrain control module (PCM).
During operation, the PCM supplies the ground path for the cooling fan relay through the cooling fan relay control circuit. This energizes the cooling fan relay coil, closes the relay contacts, and supplies battery positive voltage from the cooling fan fuse through the cooling fan motor supply voltage circuit to the cooling fan. The cooling fan motor is grounded through its own ground circuit.
The PCM commands the fan on under the following conditions:
?€¢
Engine coolant temperature exceeds approximately 106?°C (223?°F).


?€¢
A/C refrigerant pressure exceeds 1310 kPa (190 psi).


?€¢
A/C is requested and vehicle speed is below 100 km/h (62 mph) with A/C pressure above 1413 kPa (205 psi).


?€¢
Vehicle speed is less than 8 km/h (5 mph) for more than 750 seconds. The fan will turn off when vehicle speed is greater than 8 km/h (5 mph) for more than 20 seconds.

1994 Chevy Cavalier fan won't come on


Sounds like the sensor is not reading the coolant temp, or the computer is not accepting the data from the sensor.
Its possible you have air in the cooling system, or you have a problem with the computer.

  • Low engine coolant level
  • Leaking or stuck open thermostat
  • Faulty cooling fan (running too much)
  • Faulty coolant temperature (ECT) sensor
  • Faulty intake air temperature (IAT) sensor

test your fan motor.run b+ and ground to your motor and see if it runs.if it doesnt it is probably your coolant fan switch located on the cylinder head or the coolant fan relay.hope this helps.keep posted.

Coolant temperature relay switch


Most vehicles use a coolant temperature sensor which is located near the thermostat directly connected into the coolant line, or near the thermostat housing, there are relays for the cooling fan which is usually located in the power distribution box under the hood.
