2004 honda civic ex neither radiator fan is turning on?
Yesterday I was driving home and noticed that my car was starting to overheat when I was idling at a red light. The heat started to blow out cold air as the car temp. Went up. When I started to drive again the heat worked. This morning I checked under the hood and realized the first cooling fan did not work and the ac/heat fan did not turn on either.
I check the fuzes and antifreeze so was wondering what else can cause the fans to stop working
Stolen from another post:
"You have two screw in electrical thermostat's that are installed near the water jacket housing of your motors thermostat It's where one of your radiator hoses connects to the engine block.It should be the top one on the block. There will bet two temperature sensors that are about the size of a spark plug that screw into the block where the coolant is circulated through the block.Each has two wires harnessed together that plug in to the end of the sensor that isn't screwed in. One is called your fan switch and the other is your temperature gauge that shows how hot the engine is. The part you always see is in your dash next to the speedometer. They both look the same basically so you will have to unplug the wire harness from one of the two and then check to see if the temperature gauge next to the speedometer is still reading how hot the motor is. If it is then you have unhooked the fan switch and more than likely your fan will start blowing. If it seems like the fan is hard to turn by hand then you need a new fan motor. The fan switch is only about 20 dollars at an auto parts store and it's very simple to replace. What ever you do don't try to cut the fan wires and hot wire them to the two battery posts to make the fans start to blow, either replace the fan switch or you might have to replace one of the fan motors. "
The electrical radiator fan switch module needs to be replaced /or/ the fan is faulty. Go to a Honda Dealer and have all three parts checked out.
- Why could my 2000 Honda Civic show it's going to overheat I have coolant a new radiator a new radiator cap a new temp gauge switch and? A new thermostat head gasket is fine could it just need to flushed and a new water pump and timing belt
- Cooling fan not working, 2004 Honda civic? I've unplugged the temp sensor and put a wire in the plug to test the fan and it comes on when I do that, so the relay has to be working and the fan isn't broken either. I switched the Temperature sensor hoping the old one was just broken, but my car's still over heating and the fan won't come on. It was working perfectly fine until just last week. Anyone know what the problem could be?
- 1999 honda civic sedan lx a/c condenser fan won't turn on? I checked the fuses all good. Checked the relays all good. Also checked the voltage at the connecter and it's receiving 12v. The radiator ran is running. The compressor itself engages. The a/c is on and the fan still doesn't turn on I've checked the fan using an 12v dc power supply and it worked. So what could be the problem. Blower motor also works.
