Rear blower runs really slow

Hi and thanks for using 2CarPros.

If the blower motor runs on all speeds (regardless if it is fast enough), the resister is not bad. When the resister fails, the fan will only run on high.

Here are the directions for removing the motor and checking it:

REAR BLOWER UNIT
INSPECTION

1. Connect the battery voltage and check the blower motor rotation.

2. If the blower motor voltage is not operated well, substitute with a known-good blower motor and check for proper operation.
3. If the problem is corrected, replace the blower motor.

REPLACEMENT

1. Disconnect the negative (-) battery terminal.
2. Disconnect the connector (A) of the blower motor.
3. Remove the blower motor (B) after loosening the mounting screws.

4. Installation is the reverse order of removal.

The fan motor is in the rear quarter panel of the vehicle. See picture 3

Let me know if this helps or if you have other questions.

Take care,

Let me know what you find. Also, this vehicle does not have a traditional blower motor relay. It is controlled differently, so I am hoping it is a motor issue.

Let me know,

Welcome back:

It sounds like the mode door actuator is the problem. Here are directions for replacement. Also, the attached picture correlates with these directions.

Let me know if you need anything.
