How to tell if a ceiling fan has no power?
If there is no power you want to check the circuit breaker first to see if it is tripped. If you have no power at all that is the likely culprit. Do you have power to the switch and the fan still will not work. Check the article ‘ Wiring a Light Switch ‘ for information on how to tell if the switch is bad. Is it the fan that won’t work?
How can I tell if my air conditioner pressure switch is bad?
The first sign that the air conditioning pressure switch is bad is when the system shuts off intermittently. This shouldn’t happen with the windows wide open. Pop the hood and look for the condenser. It is a grille-shaped or block component that connects to the compressor with tubes and hoses.
Why is the radiator fan relay not working?
If you don’t get ground on pin 3, the ECM is not activating the radiator relay. That can be caused by a faulty engine coolant temperature sensor or a wiring problem between the ECM and pin 3. If you do find ground on pin 3, jumper across pins 1 & 2 in the socket. If the radiator fan runs, then the radiator fan relay is bad. Replace it.
How can you tell if a Hyundai radiator fan is working?
If you see battery voltage, that confirms the engine control relay is providing power to the control coil side of the relays. With the key in RUN position, turn the AC ON. Then check for ground on pin 1 in the condenser fan relay socket. If you detect good ground, the ECM is operating properly
Why is my Hyundai Accent heater fan not working?
Turning your fan switch all the way up should bypass the blower motor resistor, but as you have tried that and it still doesn’t work it’s unlikely to be the resistor, which leaves the other options. With the fuse, I’d replace it entirely and thoroughly clean the connectors in the fuse panel.
Where is the blower motor on a Hyundai Accent?
Turn on the power to your blower motor. Now locate the motor. It’s usually up under the glove box area on the passenger side. Under the dash in the very right corner. If you can find it, take a large ratchet and rap on the bottom of the motor.
What to do if your heater fan is not working?
If you can find it, take a large ratchet and rap on the bottom of the motor. If it suddenly kicks on, the blower motor is bad. If still no power, check your fuses. If fuses are good, then I would replace your blower motor resistor. Not sure where that is located on your car. It may be up under the dash by the blower motor.
What causes a cooling fan relay to stop working?
