Buy manual at auto parts store, check fuses by pulling proper fuse and looking for burnt look or metal missing, listen for relay tripping

I had this same problem about 4 months ago, turns out then fan relay went bad, I didn't have time to deal with it at the time to fix it myself... I should have made time. Turns out it was a big job that required pulling off of the front bumper, headlight assembly in order to get to the relay (I think the grill had to come off too but can't remember). Apparently our 2003 jeep GC have this problem, I have a co-worker who's buddy had this thing blow often and he actually reloacted the relay at the top of the engine compartment because of the frequency of this mechanism failing. He used it to tow a large boat of rugged terrain, hope only once is my number. Good luck, hope this helps

1995 Lt1 Camaro cooling fans operate like this; Cooling fans (2 fans) come on 30 seconds after start up on high, stay on while driving, and turn off when brakes are applied. Stock car, no mods.


Did you have it checked for DTC'S - diagnostic trouble codes ? The cooling fans are controlled by the PCM - engine computer , with the use of three relays ,located in the under hood electrical center . Do you know how to do electrical testing ?

I had the radiator to my saturn replaced bacause it was cracked. Now when the engine is turned on, the fan works, then stops. Can someone help?


you will need to change your relay most likely in your fuse box ,,put some glasses on to see the fuse diagram to find your relay ...change it ,,,it is wearing out and causing your fan to kick off and on

Does the radiator fan of toyota touring immediatly the car had been started


I would assume you have electric fans on your radiator. If you have air conditioning and it is on - then fans will run whenevr the air is on.

If you dont have air or it is turned off - and the electric fans start up immediately and dont turn off - then likely you have a stuck relay. Check your fuse area in the engine bay - there should be a series of relays. Check your fuse cover or service book for which one runs the fans. swap with another relay just to try. if they dont come on - bingo - go spend $10 and buy a new relay

My cooling fans are not coming on


3 things to check here assuming the fans are good. Fuses and relays, wiring and connections or fan temp sending unit. Dont think because the sender for the guage working indicates that the fans should work. Most cars have a seperate sensor for the fans. I dont have a wiring diagram so I cant tell you where the relays, sensors or fuses are on this model but this should at least get you started in the right direction.
Hope this helps... Dale

Windows wont go up on 2001 ford mustang dont have fuse diagram


The fuse for the power windows is a 40 amp. fuse in the fuse/relay box located under the hood on the drivers side of your vechicle.
It's the first top fuse (position 12) next to the relays.
To see a fuse block diagram go to this FREE Ford website and download the owners manual for your vechicle. It's location in the manual is "roadside emergencies" page 136.

98 honda civic engine overheats, cooling fan does not turn on


Under the hood of the engine, close to the battery, there is a black plastic box. This is the Fuse Relay and Control Unit Box location. Remove this Box cover. The top of this box shows which fuses or relays control the different electrical components within the engine. On the Drivers's Side of this box (right-side if you are leaning over the bumber and radiator, and facing the windshield) you will see a radiator fan relay. You can pull this and take it to your local Parts store and ask them to test it. If it tests bad, then buy another (likely $20+). Do NOT keep driving your car until you get your radiator fan fixed, <this image should help you>80dd710.png because over-heating the engine could ruin your engine ($$$$).
