Cooling fan wont come on?
i'm assuming you mean your computer processor fan. If so, replace it. It's dead!
When you say "cooling fan", do you mean the radiator fan or the cabin air fan? If the radiator fan and the compressor are failing to come on, it could just be low refrigerant but in either case there is no guarantee that any single component would cause what you describe. It could be a fuse, relay, controls, connector or any of a number of possible causes.
Answer The cooling fan is not on all the time. When driving above 35 mph, ram air takes effect and the air going through the radiator is stronger than the air can be pulled by the fan. When first starting the car, it may take several minutes for the fan to come on because the engine is "warming up". The cooling fan is controlled by a thermostat. It is supposed to come on at a…
You replaced the relays in your 1997 Toyota RAV 4 and the engine cooling fan does not come on when it's suppose to What else can you check?
When 1990 Honda is running cooling fan does not come on but comes on when shut off thermostat and temperature switch changed?
There could be 3 or 4 reasons for this... First, check the simplest thing, the fuse. Next, check for a faulty fan thermostat or damaged wiring to the fan. Lastly, it's possible the fan motor itself is faulty. i come to find that if your Honda civic has a coolant leak and runs hot...... your thermostat will be stuck in the closed position and wont allow the coolant fan to come on
My 89 Pontiac 6000 cooling fan will not come on though Fan is okay and temp sensor replaced and relays ok but fan works only when temp senor unplugged or air is on so what do I do?
The cooling fan light on your dash refers to the engine compartment cooling fan on the passenger's side of the vehicle, not the radiator cooling fan. In my experience with my '85 Mr2, that fan doesn't do a helluva lot, cuz mine only works if I unplug the temp sensor (sensor's dead and I don't wanna replace it) and I've never had a problem with overheating.
Where does the power wire from the fan motor on a 1994 Ford Escort LX connect to the fan control switch?
There is no fan control switch, and no direct connection to any sensor or switch on that vehicle. The system works like this. The computer(PCM) decides when to turn on the fan. The PCM looks at engine temperature from the ECT sensor, and AC input from the AC control head switches. When the PCM decides that you need the cooling fan to come on, it uses the cooling fan relay, and the cooling fan high…
