What should I do if my Bentley Blower Motor is not working?
You say you’ve checked the fuse and replaced the resistor. Wiring rarely breaks, so the next logical step is to access the fan motor per instructions in the Bentley service manual and use a multimeter to check for power at the fan motor connector when the switch is on.
Why is the motor on my blower not working?
If there is power, pull the connector off the motor and use your multimeter to check the motor for continuity. No continuity = bad fan motor. As an aside, a fan motor with bearings on the way out draws extra current and often causes the resistor to overheat, so if you replaced the resistor because it popped my money’s on a worn fan.
When do you need to replace the blower motor relay?
If the blower motor does not function, car fuses are blown, or relays are melting, you may have to replace the car blower motor relay. 1. Blower motor does not function 2. Blown fuses 3. Melted relay The blower motor relay is the electrical switch that is used to supply the power for the vehicle’s blower motor.
Where is the blower control switch on the dashboard?
The blower control switch on the dashboard controls the circuit flow of the blower motor to adjust the voltage from low, to medium, to medium-high, to high. When on high, the circuit bypasses the blower resistor.
Can a bad ground cause an AC blower to fail?
Never rule out a bad ground. It certainly is not always the problem, but the grounding circuit is every bit as important as the positive (negative in some cars like my old Sunbeam Imp). It fails less often, but it can fail. The heater/ac blower does not come on.
Can a blower fan fail on an AC heater?
It fails less often, but it can fail. The heater/ac blower does not come on. Can hear AC compressor kick on, but just no blower fan. The electronic display for fan just goes up to full then back down. Checked fuse, okay; checked volts at wiring leads have full 12volts.
