SOURCE: fan runs all the time when car is on

I did the same thing and had the same problem. I believe I replaced a ten amp fuse in the engine compartment and fixed it. Really pissed me off.

SOURCE: blower motor location 1990 geo prizm

In my 1992 it is underneath the dash on the passenger's side, but you have to take the whole front panel including the glove box off to access it. When that is done there is a rectangular housing and a more circular housing. On the bottom of the circular housing there are three screws that hold the blower motor up. Remove the screws and it will drop right out.

SOURCE: The radiator fan on my 1992 Geo Prizm will not

pull the cooling switch/sensor Usually the one next to or on thermostat housing. I do believe it a 2 wire. the 1 wire is for your guage. I think you can short it and see if it comes on. take a wire and plug into each other creating a complete circuit. if it comes on then replace the sensor which I think is your issue anyways.

The fan is not working on my opel corsa utility 17 dti 2005


Fuses ok? The fan (I presume we are talking about the radiator cooling fan) is controlled by a thermostatic switch. You need to check that this switch is closing it's contacts when it gets hot (and this most likely is the cause of your problems) If the switch is functioning correctly there will be a relay which it controls. The next thing is to check that this relay is switching when the thermostatic switch closes. If the fuses are ok, the thermostatic switch is ok, the relay is ok, then check at the fan plug that you have voltage when the fan should be running. If you have voltage and the fan does not run, the fan motor is U/S and will have to be changed. If you have no voltage then you have a wiring problem. As I say, the most common failure item is the switch, followed by the relay.

Renault laguna engine fan not coming on and engine overheats and red warning light comes on and says to stop. coolant ok but everything gets really hot. ok when doing long journey but not when stopping and...


Hi,
The problem would be the radiator cooling fan.
  • Check first the relay, interchange that relay from similar one in the fuse box in the engine compartment.
  • Check the radiator fan motor, pull down the fan motor and directly connect it to the battery.
  • Check the cooling fan thermo switch, it is located underneath/side of the radiator assembly. To check it, just get a paper clip and short the socket connector, fan should run if not the relay has a problem or the fan motor is already malfunctioning.
Hope that helps you out.
Tanks for asking FixYa!

Some thing too check:
Make sure coolant level is up to line and clean (not dirty, do to clogged radiator, may need to be flushed or replaced).
Make sure air flow through the out side of radiator is clear (dirt, leaves, ect..) .
Make sure fan is working properly equip t (is not running too slow). Or Manual (belt driven) fan clutch is working properly, not loose or spinning too freely?
Check for broken or cracked fan blades itself.
Check radiator cap, (no gasket tears).
Could be thermostat going bad ?
Could be coolant temperature sensor/switch (from computer) going bad?
Check radiator hose(s) (too soft, may collapse)?
In some rare cases:
Timing could be off.
Could be water pump.
Could be blown head gasket(s).
Could have cracked head(s).
ECT..............Hope this was some help???

Engine fan does not turn on


Look on the radiator for a switch (Physically screwed into the radiator) with 2 terminals on it.

Pull them off and short them together with a piece of wire. (Jumper) If the fan runs your thermostatic switch is bad.

The switch is a real common failure.

If the fan does not run... check the fuses.

If fuses are ok then check the fan winding for resitance with an Ohm meter.
No resistance = burned out fan motor

Thanks for using FixYa!

The radiator fan on my 1992 Geo Prizm will not come on. I have tested the fan motor via a wire by pass and confirmed the motor is good. I have also replaced the relay and still the fan will not come on....
