Blower motor heat does not work

HVAC climate contol , Heat an A/C blower motor not working ! The blower motor works for both heat an A/C . Manual or automatic climate control ? Blower motor is bad or blower motor control module is . videos on youtube on testing blower motor electrical circuits .

This is a problem that is due in every case to a failed blower motor speed control resistor. the blower motor resistor is located right next to the blower motor and the wiring harness connector sticks out of the air ducting that cools it.

check see if power going to blower motor using 12 volt tesl light.if yes, remove blower motor, hot wire it.if blower motor works problem in the control switch or short in blower motor wiring,if blower motor dont work when hot wired,blower motor is bad.

Its either a bad connection on the blower motor resistor or a faulty blower motor resistor.These are known for over heating.

under the passenger side of the dash right above the passengers feet. With the key on and the blower set to high tap the end of the blower motor with a screwdriver. If it starts to work replace it.

CHECK HVAC FUSE AND BLOWER MOTOR FUSE AND RELAY.IF ALL IS GOOD CHECK FOR POWER TO BLOWER MOTOR.YES BLOWER MOTOR DEFECTIVE.IF NO POWER GOING TO BLOWER MOTOR AND ALL FUSES AND RELAY GOOD.YOUR HVAC CONTROL SWITCH IS BAD OR YOU HAVE BROKE OR LOOSE WIRE AT CONTROL SWITCH.

The blowers ion the back have there own blower motor. The front has it's own. The resister controls the range the blower motor runs on,( low, medium, high). If the blower motor is not working it may be the motor itself. Was the fuse checked:?

first, check the fuse for the blower motor. If ok, you may have a bad switch or bad blower motor. If you are a techie, you should jumper 12 volts to the blower motor hot terminal. see if it blows then. You also have a blower motor resister that gives you the 4 blower speeds, but usually when it fails, you have high speed only.

good luck

blower motor resistor is in the front (right?) wheel well.

If you can, check if there is voltage at the blower motor connector with the ignition on and the engine not running. If you have voltage, the blower is bad. If no voltage, it may be a bad blower switch, the blower motor resistor assembly, or the wiring between them.

The resistor assembly is on the evaporator housing under the dash on the passenger side and near the blower motor. The glove box must be removed to check this and the blower. A thermal limiter resistor is built into the resistor assembly and will open, ie melt, with excessive heat.

Without more details on this, it appears either your blower motor or the blower motor resistor assembly is bad.
