Intermittent blower motor

This Honda Accord is having trouble with the HVAC blower motor. This vehicle the blower motor woul. It is located directly under the glove box . Well now the blower quit again. Please, if you have any info, .

Fuse is goo fan motor removed and connected to power and works fine.

Owners may experience an intermittent heater blower fan, on one or more of the speed settings, or the fan may not work all, or will only work on full power, or may be stuck on full.

Otherwise known as the Heater Blower Resistor, Resistor Pack, Heater Rheostat or Blower Motor Resistor, Part No. Now that summer is here, the intermittent issue returned. Envoy XL with the automatic (electronic) HVAC controls.

I pulled the connector out and checked the voltage at that plug.

V on all levels of fan setting. I even hooked 12V from the battery . Edit:After more investigation and reading about the blower motor resistor pack, I decided to locate it to check. RealOEM and the Haynes manual: RealOEM.

The most common cause however is: A faulty Heater . When the resister of the blower motor starts to fail, the motor operates only intermittently. The higher current can make the jump across the resistor contacts that are going bad and get the blower motor to . An other source of heat can be from blower wire connections to large power resistors used to reduce the voltage to the blower motor , and thereby reduce the fan speed at lower settings. Wires connected directly to voltage-dropping power resistors (generally these are white ceramic packages) will have heat . Just to let you know, I did replace the blower motor voltage regulator. But the AC would still only turn on intermittently.

Sometimes it works, most times not.

Seems to be improved by jiggling the wires under the dash. Ford Expedition intermittent front blower motor operation. Replaced the motor, did not correct the issue.

Verified motor is operational, and problem seems to be in the controls.
