You can determine if a fan relay is faulty by checking for signs such as the fan not turning on when it should, or if it runs continuously without stopping. Additionally, testing the relay with a multimeter for continuity when activated can help confirm its functionality. If the relay clicks but the fan still doesn't operate, it may be defective. Lastly, inspecting for any visible damage, burnt contacts, or corrosion can also indicate a problem.
What else can I help you with?
Why Motor fan not working?
Could be a faulty fan motor, a faulty fan motor relay, a faulty fan motor temp switch or a blown fan motor fuse.
What would make the radiator fan stop working on neon?
A faulty fan motor, A faulty fan motor relay, A faulty coolant temp sensor, A faulty ECM, (most unlikely),
Why is heater fan blowing Peugeot 306?
Could be a Faulty relay.
What will stop the rad fan from working the fan is free it will not cut in to cool the rad down?
Could be a blown fuse or a faulty circuit breaker, a faulty relay, a faulty temperature sensor or the fan motor may be at fault.
What do you do if the fan on a 1994 Hyundai will not stop until the battery runs dead?
you might have a faulty fan relay that is stuck closed, allowing fan to run at all times or a faulty coolant temperature sensor. the fan relay contacts have welded shut it needs replacing just pull out the relays one at a time until the fan turns of and replace it alternatively temp sender could be faulty but this is unlikely
Your 96 Saturn is running hot after about 15 miles?
Causes of overheating: Low/no coolant; cooling fan relay switch/sensor faulty; cooling fan motor faulty; thermostat stuck in closed position; water pump faulty.
How do you test Fan relay Honda civic?
To test the fan relay in a Honda Civic, first, locate the relay in the fuse box, typically under the hood. Use a multimeter to check for continuity by removing the relay and testing the pins; there should be continuity between the terminals when the relay is activated. Additionally, you can swap the relay with a similar one in the fuse box to see if the fan operates. If the fan works with the swapped relay, the original relay is faulty and should be replaced.
What are P0480 and P0633 codes on a Chrysler Town and Country?
P0480 is Cooling Fan 1 control circuit malfunction.Possible causes.- Faulty fan control relay- Fan control relay harness is open or shorted- Fan control relay circuit poor electrical connection- Faulty cooling fan 1- Fan cooling fan harness is open or shorted- Fan cooling fan circuit poor electrical connectionP0633 is SKIM key not programmed in computer.Possible Causes.- SKIM module must be programmed into ECM- SKIM module defective
My rad fan only works the odd timesometime you have to hit the relay with the tip of your finger to get it to work put a new relay on but the same thing happens.?
It would probably be nice to know what we are working on. I had a similar problem on a 1994 ford escort, and it was actually the relay block where the relay plugs in that was faulty. Hope this helps.
What causes the air condition fan not to come on?
faulty thermostat, stuck fan relay, bad fan motor, no voltage to motor, bad circuit board, bad run capacitor...
What would keep the engine running cold in a 96 Pontiac sunfire a faulty Engine Coolant Temperature Sensor or a bad relay for the cooling fan which keep the fan always running or both?
more likely to be a faulty coolant sensor or the thermostat is faulty and staying open
Why would the cooling fan not be coming on?
Faulty electrics. Thermostat, relay, fuse, fan motor, short in wiring, poor ground. Unfortunately, you might have to have a professional look at it.
