    Hot wire the fan to the battery. If it works it's fine. I've got no idea what a "thermostick" is but you will likely be looking to replace the relay behind and below the right headlight.

Check out the fan switch. It's expensive but easily changed.

Cooling fans are not coming on, what could be the problem?


Either the temp sensor is bad, or the relay is bad. or the fan motor is bad. Or you have a blown fuse.
Look for fuse first.... To test if fan motor is bad disconnect the connector to the fan and jumper it to the battery.if it spins it's good. the other two. use a component locator to find their location and replace. they are inexpensive. Temp sensor is in the cooling circuit (radiator...maybe next to thermostat) the relay will be in a fuse box under the hood.

2003 Jeep Grand Cheeroke radiator fan runs when car is off draining battery. Could it be the relay? If yes is the relay in the fuse/relay box under the hood or under the passenger headlight?


After checking the conventional relays and fuses, we found an additional auxiliary cooling fan relay behind the front bumper. Once replaced, all is well.

The fan relay is likely shorted and keeping the fan motor energized; to check this you can remove the relays from the fuse panel... remove the cooling fan rely from the underhood PDC (Power Distribution Center). Fot this and additional fuse details, check this link: wjjeeps.com/fuses.htm

Hope helps.

I recently bought a 99 chevrolet cavalier LS 2.2 from the time i drove it home it started heating up,so i replaced the thermostat filled it with anti freeze and it still guage read 195 degrees and fan...


If there isn't actually any coolant dripping out of the engine, or rad, or hoses when it is sitting, either running or not, you most likely have a blown head gasket. The easiest way to check is, when it is cool, remove the radiator cap, and start the engine. If bubbles are constantly rising to the top of the rrad, your head gasket is gone, and i can almost guarantee you that is the problem. Sorry.

Replaced the thermast and relay switchfan running but car still running hot at 255 260 degress what to do???


I would do a compression check on the engine. Also pull the radiator cap , (after the car is cool) and see if the coolant is moving smoothly when you get it back up to operating temp . Leaking head gaskets can cause engine to over heat, so can bad water pump, plugged radiator core, and so on.

My 1999 DeVille Concours A/C and heater fans don't come on.


open hood,look in main fuse box for blown fuses,or bad relays to heater fans. the a/c fan should come on only when you turn a/c on at the dash panel only. it has nothing to do with the heat. if the heater blower fans don't come on, then look in the main box[fuse] for a blown fuse also. otherwise the problem is in the heater control module.[where you turn on a/c and the heat] that panel has a different fuse location.under the dash drivers side or on panel on drivers door at the door jam[where the door shuts towards the front of car,under mirror,but inside] look for fuse panel there also for blown fuse. hope this helps,but if not,recommend you seek a pro.such as cadillac

What if the fan don't work?


check main fuse black box under the hood. look for a main fuse or relay bad. also the fan could be bad, try running the engine to operating temperature,. then look at the fan under hood to see if it's turning. the only way to be sure if fans turning is to see it turning. if you turn the key on, do you hear it come on? when cool? it should'nt come on until the engines warm!! the a/c fan will come on when you turn the air conditioner on, or it should. check for blown fuses in main fuse box under the hood in black box. thank you for choosing fixya.com

Blower motor to heat and defroster does not work


you may only have a blown heater blower fuse, look in the fuse box for a blown fuse.check both fuse boxes, including the black fuse box under the hood. if fuses are good, try tapping on the fan box on driverside under dash, sometimes leaves get in it and stop it up. if you don't find the fan box under passenger side dash, look under hood on passenger side on firewall. hope this helps and thank you for choosing fixya.com

Engine low coolant light on. looked for leak in engine compartment,none found. Topped off tank with red vw coolant. Went a few days and light came on again. This time a little fluid on garage floor....


You can idle the car up to operating temperature to see if the cooling fan engages. there is a fuse for the fan, it's a 30 amp breaker located in the fuse panel mounted under your hood right on top of your battery. Your Owners Manual should have an illustration.

My chevy venture 2003 only over heats when it is still with the engine on but it does not over heat when i drive it, what could it be?


Odds are your electric cooling fan[s] isn't coming on. This fan should only run when the a/c is on or when the engine temperature has reached about 218 degrees. Once the a/c is off or the engine temp drops to about 210 degrees it shuts back off again. It rarely comes on at speeds over about 35 mph because at that speed enough air is forced through the radiator to keep the engine at about 198 degrees. I would start by looking for a blown 30 amp fuse under the hood. There may be two of them marked "Cooling fan 1" and "Cooling fan 2" or something similar. If the fuses are good you could have a faulty cooling fan motor that just isn't running. Hope this helps a bit!

Need to know the fuse for the electric cooling fan.


Try looking in fuse/relay power distribution box under hood . Should be labeled underside of cover.
