Check the fuse under the drivers side or the passengers side.

Location of thermostatic switch 1993 Buick Regal 3.8 motor fan motors don't run


The fans are controlled by the ECM and it uses the ECT sensor for temperature sensing, so if the check engine light isn't on the sensor is not the problem. You need to have an active test run on the fan system to see what code is returned. Have you tried powering up the fans at the relay?

I have a 2003 jaguar x type 2.5 the cooling fans not working and over heats


cooling systems are the same for all vehicles, depending on years ,, in your case all you have is a fan, relay, and sensor, controlled by a circuit with a fuse, so , always check fuses first, if bad replace,, if not, unplug the fan at the connector,, use a jumper wire to supply the fan with 12 volts direct from the battery ,, if it starts, its not the fan, if it doesn't the fan needs replacing, if that checked out to be good,, backtrack to the fan relay, ( usually the problem) locate it in the under the hood fuse box, it will be listed on the tag on the underside of the fuse box cover ( or in the owners manual itself) you should have a couple of the same relay in this box,, ( Jaguar uses the same relay for a number of items) locate the one for the fan, and switch it out for one that runs a system you know is working, start the vehicle,, and let it run until the thermostat opens,, watch the temp gauge don't let it move up to high. soon after , the fan should start , if by now the system isn't working, its going to normally be a short in that circuit, and would have to looked at by a trained professional with knowledge in electrical circuits

2002 ford taurus overheats. Just replaced radiator, waterpump, thermostat and heater core. what else can i do to repair. also, ford flushed the system.


About the only thing that you didn't list is the cooling fan. Are you sure that it's working properly? Drive the car until the engine starts to get hot. After awhile you should hear the cooling fan come on. After you have driven the car for a while, park it and open up the hood. If the upper radiator hose is almost too hot to touch, then check to see if the coolant fan is running. If it isn't, then turn the AC switch to "AC MAX". If the fan still doesn't come on, then a malfunction is indicated. Try to locate the fan control relay and swap it with another relay that has the same part number. Use a relay that will allow the engine to run. Allow the engine to reach operating temperature and see if the fan comes on after switching the AC switch to "AC MAX". If the fan now operates, then replace the relay. I hope this is helpful to you. Thank you for trying Fixya.com. If this does not solve your problem, then post a comment and I will respond by getting into more advanced diagnostics.

Niether of my raditor fans turn what should i check first


Short out the thermostatic switch on the radiator. If the fans turn then, the problem is the switch. If not, check the fuses or there could be a relay that is not working, check the hand book or the fuse box for the location of the fuse and the fan relay.

Cooling fans will not come on


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!!

Coolant fans on a 92 coupe deville


You checked the fuses, that's a good place to start. Usually electric fans are powered up using a relay. It's likely that each fan has it's own individual relay so it's strange that niether fan works. Is the engine overheating? Try turning on the air conditioner after starting the engine. One of the two fans should definitely turn on immediately after switching on the A/C. If so, then the other fan, which would be controled by the temp sensor circuit, might be bad. Before replacing anything you may want to check the temperature sensor is working properly. The relay(s) are probably located in the engine compartment usually near the firewall. Hope this is helpful, if so, please remember to rate my response. Thanks.

Blower Fan not working


Could be a fuse or a relay, they are usually under the hood in the "Fuse/Relay box". The exact location should be indicated in the box cover and/or the owner's manual of the van. To try the relay, most of the relays in that box are the same, you can try switching it with another one and see if it works. But, i suspect a possible bad blower fan motor, they seem to go quite often on Econoline vans. They are a pretty simple item to replace, located under the hood on the passenger side, on the firewall. To diagnose for a bad motor, unplug the plugin on the motor, and with the key on, heater control to max, use a test light or a multimeter to check for power and ground at the plugin. Another thing, is the fan not working on all speeds, or is it working on max speed, the reason for my question is, if it's only working on max, the resistor (used for lower speeds) is probably bad. It is located close to the motor in the airbox on the passenger side of the firewall.
