2006 Malibu cooling fans

Asked by 03expedition94sierra... Feb 21, 2018 at 11:20 AM about the 2006 Chevrolet Malibu LT FWD

Question type: Maintenance & Repair

The cooling fans only come on when the ac it turned on
otherwise they are not coming on I checked the codes
and there is a p0442 code on there. I have replaced the
thermostat, purge valve, Evap canister vent  Solenoid. The
car also starts ok when it cold but when it’s warm it acts
like it’s not getting gas but it is. Once you turn the key and
you hit the gas pedal a little it starts but it idles rough I
can’t figure this out

The gas/hesitating start are likely related to the OBD trouble code/EVAP system leak. But that should not prevent the cooling fans from coming on when engine is running hot. You'll have to diagnose the cooling system, make sure fluid level is good, the fluid itself is good (and not rusty gunk), and flow is good. Check the engine coolant temperature (ECT) sensor is working, it can be tested with a meter and pan of hot water. (Some models have two coolant temp sensors, one for input to the engine's computer, the other is a sending unit for dash gauge - you want to make sure you have the ECT.) You can also confirm the fans work by grounding the fan relay or jumpering it to provide power to them. The fans are actually controlled by the PCM.

Ok the coolant looks good and it’s full I have had ideas about the temp sensor but was wanting to find out on here if there have been simalar problems. I’ll Chen the sensor and I’ll see what that does
