Why does my car blower fan not work?
If little air is coming through the vents (hot or cold), then it could be because the blower motor for the fan or a switch or resistor that controls fan speed isn’t working. Another cause might be that the electronically controlled “blend doors” that direct air flow are stuck or broken.
What causes a heater fan to stop working?
Blower motor resistor / control module problems In some cars, a failed blower motor resistor can cause a heater fan to stop working completely. In most cases, a blower motor resistor fails due to corrosion or overheating.
Where is the fuse for the AC blower?
Fuse Protection To protect the blower motor power circuit, a 20-, 25- or 30-amp fuse is usually located in the fuse panel under the dash. The rating of the fuse will depend on the vehicle application and how much power the blower motor requires at full speed.
How do you test a bad blower motor relay?
Connect a test light or multimeter to the ground (black lead). Turn the ignition key to the on position (engine off), and remove the relay. Using the probe, test all terminal sockets in the relay connector. Two of the four should have power.
Why is my Volkswagen blower motor not working?
I put an electric heater in the passenger footwell to heat the motor and after about 45 minutes, turned the vehicle on and it worked again. The same problem occurred about 3 times this winter.
Why is my VW Jetta cooling fan not running?
I have a 2008 Volkswagen Jetta S and it cooling fans are supposed to run when the engine gets too hot as expected. But out of 2 fans, the smaller fan is not running. Could it be because of a blown out fuse?
Why is my blower fan not blowing air?
The blower fan resistor is a simple electronic circuit that changes the resistance of the current sent to the blower motor, and enables multiple fan speeds. If you find the blower fan works, but only at a single speed setting, the blower motor resistor has probably gone bad.
Why is the blower motor on my 2007 rabbit not working?
If blower motor works on full speed then it is the resistor which is under the glove box on 2007 rabbit. Video on YouTube available. I have same issue, fuses are fine, fan does not work at all, have pulled blower and applied power- it works.
