There is a temperature switch on the passenger side bottom of the radiator that has a wire connector attached to it. The switch screws into the radiator and then the wires connect to that. That switch is what tells the relays to turn the cooling fan on. If your fans don't turn and the engine is running hot you can test the switch using the following steps. 1. turn the ignition to the on position but don't start the engine. 2. disconnect the wire connector to the switch on the bottom of the radiator. 3. using a small jumper wire, jump the two wires inside the connector. If the fans turn on then you will need to replace the temp switch. If the fans still don't turn on then you will need to check the fuses, relays, and the fans themselves.
damaged fan blade.replace with oem fan assembly.
Unscrew the bolts that connect the fans 2 the radiator then unplug the plugs and it should come out..
I just went through that exact problem with my 88 prelude, it was the ignition cylinder.
You cant replace it, it's all in one piece.
Stand in front of the car facing your back to it and then bend over...the cooling fan will plug in itself.
Honda cars are designed to do this. When the engine is warm the fan will run up to 15 min. after turning the engine off.
not likely as the heater fan only controls the air in the cabin, maybe the radiator fan has gone out too?
blower motor is under the passenger side dash board 3screws and it comes out there should be a ta on the fan pry it out towards the finsof the fan and the fan should come off might want to spray with some wd40 should help probable on there rilly tight
fan is hitting where the dent in the oil pan is
One fan only comes on when the A/C is activated and runs continuously as long as the A/C is on. The other fan only comes on when needed to cool the engine down as in city driving.
It is bolted to the driver's side front of the engine bay right near the AC Dryer. There are two relays there one for the AC Clutch and one for the condenser fan.
When 1990 Honda is running cooling fan does not come on but comes on when engine is off and I thermostat and temperature switch changed?"
better if come with a dia.
If you are talking about the coolant temperature switch that turns the fan on when the coolant reaches the right temperature, then mine it is located in the bottom of the radiator directly under the fan.
Check the thermal relay.
Probably because either the fuse or circuit breaker or the temperature sensing switches have failed.
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
Check the cooling fan relay and the control sensor. Check the fuse as well and if these are all good, check the fan motor.
Blown fuse. Defective fan motor. Defective thermal relay. Wiring problem.
on a 2003 Honda si the fan motor blows shen removed from car. there is 12 volts to fan . fan will not run when plugged into car. does fan sw have anything to do with this
Check the integrity of the wiring. Determine if the fan motor is burned out. More likely, the sensor has malfunctioned. Unplug the sensor (engine off) - the fan should come on when the ignition is turned on. If it does, the sensor is bad.
Where is the heater blower fan located 1996 honda accord?
It the A/C is on the fan will run continuously. Turn the A/C off and if the fan still comes on as soon as you turn the ignition on, the thermal relay may be stuck closed.
Mabye if you cleaned the fan out it might start to work again or the wires aren't connected.
There are a couple of reasons why a Honda Civic heater fan is not working. The fan motor may of blown or a fuse needs to be replaced.
