Yes, it's probably the PCM. I had the same problem, and upon replacing the PCM it started working again. If your cooling sending unit is new, and so many parts of your fan assembly are new, it's probably not receiving the signal from the sending unit. Hope this helps.

The fan wont work car does not get hot shut off


cooling fan works on a temp sensor in the engine block. it only turns on when the temp reaches a set limit and shuts off when it gets below a set limit.. cooling fan components are , fans, fan relay , and temp sensor . best way to test the fans would be to let the car set running and watch the temp till it goes up to 185 -195 deg. at this time the fans should turn on and the thermostat should open and cool the engine back down. also when ever the air conditioning is on so should the cooling fans be on. if the fans do not run the check all components till you find the broken one. fan relay and air conditioning relay are separate but work the same. and will interchange

Why does my fan keep running in my 2003 Volvo S 60 after the car is off?


It can be faulty fan relay.The relay is not turning the system off.Or its wire short issue.Even with ignition off ,the fan relay is getting power so its not letting the fan to turn off.Bypass the fan control relay and see if still the fan works with ignition off or not.

Overheating: cooling fan won't ingauge


I would first check the fan relays make sure they are good ..If no problem there then i would disconnect the wires going to the cooling fan..turn on your a/c ..that should activate the fan even if the vehicles cold ..see if you have voltage across the wires plug the meter right into the wire you should have 12 volts..if you do then its the fan..if the fan comes on during a/c but dont come when vehicle gets hot,then its probably the temperature senser that tells the fan to come on..Its located near the thermostat.

Cooling fans not turning on. Fuses good. Relays good.


The fan will only come on when the water temp. reaches about 80 digrees with the new water pump the temp. is staying low and the fan is not needed. Drive it a while checking the temp. guage if it over heats and the fan doesnt com on then you have a problem if not all is o.k.
