Question about 2003 Chevrolet Malibu

1 Answer

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 the temp in the instrument panel start to go up and I check the fans and they are not turning. I have check all fuses and they seem to be good. What can this be or what do I check? Thanks, Paul

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.

If it is a very loud noise, then it may be the window regulator. This is the assembly that the motor and glass bolt to. The door panel would have to come off to inspect.

I have a 02 chevy malibu My cooling fans won't turn on automatically and car begins to over heat if I turn on the a/c the fans will turn on I have recently changed the cooling temp sensor & thermostat


The fact that the fans operate when in the A/C mode means that there is nothing wrong with the fans themselves or any of their associated relays. The PCM controls the activation of the fans at all times, whether it is due to the A/C controls being on, or from sensing the coolant temperature. Thus, I'd say your problem is in the Coolant Temperature Sensor circuit. Either the replacement sensor you purchased is bad (not as likely) or there is damage in the wiring or possible the PCM itself for the circuit.

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.

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).

99 chev malibu,cooling fans dont come on


make sure it is full of coolant, next check for a bad fan relay, to see if fans are ok! run a wire from positve post on battery to positive on fan motor, ground other side if need be. if fans do not work they are bad, if they do work, check relay to fan and coolant tempurature sensor if needed.

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
