One cooling fan works the other doesnot.Is it the fan or fuse or both? thanks

Hello. Your car's cooling fan relays are somewhere in the fusebox/relay box. Also, your car has a 'fan switch' on the thermostat housing. If the 'fan switch' is in operable, the cooling fans won't work. It can be the thermostat housing seal/gasket. Good luck and keep me informed; if you want to.

no information generic answer -horn check for problem in the steering wheel -----fan -check and test cooling sensor if radiator fan--inside evap fan --check and test control - fan connections ,wiring and components

there is another coolant temp sensor that is a normally open switch. It closes when it reaches a certain temp and turns the fan on. If you are not getting 12 volts at your fan motor and your fuse is good for this circuit than you have a bad "automatic switch". that will need to be replaced

If the fan not turning on when car engine getting hot,then car will notice overheating.Click this link below for troubleshooting:---http://technoanswers.blogspot.in/2012/02/car-running-hot.html--------To know how engine cooling system works ,click the link below :----Engine cooling components working?

This will help.

Thanks.

have you checked the fuse to fan have you tested to see if the fan is bad if your getting power to fan and fan isnt comeing on then the fan is bad

fuse panel label heater . check power at fan plug. maybe fan bad or fanswitch

Hello, Are the cooling fan(s) coming on with the truck in park and the engine at idle? If the cooling fan(s) are not working A/C will not cool with truck setting still.

Hi,

Fan Relay switch is stuck open. This of course assumes your temperature sensor is working appropriately. Which I assumed since you seem to know that the engine is running hot.

Replace the fan relay switch. The relay switch is tripped when the temperature sensor tells the computer the engine is too hot.

Until you get the relay switch replaced, you can either by-pass the relay switch and directly connect the fans to the battery, or turn on your A/C ALL the time and use it at a minimum setting. This will keep the cooling fans running at all times.

Hope i helped you.

Thanks for using ' Fixya ' and have a nice day!!

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.

hello,

cooling fan not working could be a lot of things.

first , test the fan itself, put a direct 12 volts to the fan terminal and watch if it would run.( be careful of the blades ), if it does not run, could be carbon brush. replace if necessary.

if it runs, check relay circuits. one for A/C and the other one for high temperature of engine.

check also for fuses with label " cooling fan" or "radiator fan". check all fuses just to be sure.

tnx 4 using Fixya,
