Cooling fans won't come on in my 97 Chevy malibu


The PCM controls that activation of the cooling fans. I uses three relays to do this. The configuration of the relays is such that failure of any one of them should not result in total fan failure (one or both would still operate). Try this - with the engine running, turn on the A/C. If the fans work, then your problem is that the coolant temp sensor is not telling the PCM the coolant temperature properly. If they still don't work, then, although it doesn't seem likely, I would have the COOLING FAN RELAY, COOLING FAN RELAY 1, and MODE CONTROL RELAY checked. Reason being that the only other possibilities are the PCM and the circuit wiring itself.

it should be the cooling fan relay not fuse. check to see if fan motor is good . run test wires from battery to fan motor to see if it works. if it works its probably the relay

1999 Malibu Cooling fans don't come on. Country driving is fine. City driving and a few stop lights and it over heats. Temp Gauge works fine. If I un plug the sensor then fans come on but Tranny and Engine...


country driving at high speeds keep engine air cooled. but in city there is not much air to cool the engine. check the sensor for the fans. relay for fans must be ok, cause you said if you disconnect sensor then fans run. replace fan sensor. also make sure there is a proper amount of coolant in system. (do this first).

Overheating on a 2001 malibu after thermostat has been replaced. We have replaced the thermostat, however the temp gage still registers over the 1/2 way mark.


Check the cooling fan, its sensor, the relay, the fuse. On most cars the fan is not needed on the highway, but engine overheats it it doesn't switch on inside the city. Also, clean the system with a special liquid according to the directions on the can and use coolant after that, water causes corrosion. While pouring/filling/cleaning, keep the heat switch on max heating to allw circulation via the heating radiator.

2003 malibu cooling fans don't work. I have replace the relay and the temp sensor and still nothing. When ever I disconnect the temp sensor the fans come on and work normally, but later in the day I see...


okay pull the temp sensor connector ( disconnect it) and turn car on if the fans run then its the temp sensor.... part # wt3000.
Theres also 3 relays that turn the fans on in the fuse box cooling mode fan relay @15 which is part number 7234. and cooling one # 1 which is 3604, and cooling fan #2 which is 7236.
I have the same car...give me a fan clutch cooling system anyway of the week. simple and efective no problems.

Cooling fans on 2001 chevy malibu will not come on unless ac on


the relays control circuit is grounded by ECM (computer) . to check this make sure the is hot enough for the fans to be commanded on by computer and check to see if you have voltage at relay and it has ground from computer . you may need ECM.
good luck
