2001 sequoia front ac blower not working, blower motor is OK

Sounds like a Controller Issue with the Climate Control. Seeing that you applied power and it worked, then it is not the Motor.

UNLESS you try it on ALL SPEEDS and if it then does not work, you have an Input problem.

If it only works on ONE SPEED, then you have a Resister Issue for the Blower

Front a/c doesn't blow but rear works fine in my 2003 Yukon Xl

Check the blower motor for a burnt connector, they messed up on the wiring for the front AC/Heater blower, the system need to be modified with a kit that replaced the blower the wiring harness and the heater blower switch. See the local GM dealer for the details and cost.

2003 Dodge Durango front heater blower problem

The front and rear are two different systems-if the rear works or doesn't -your front still should. Your problem is the blower motor resistor and yes you can do this yourself. Remove the glovebox door and the resistor will be fastened to the heater/ac box with 2 screws and a harness plugged into it. It is a dealer only part, but they are under $30. Hope this helps you. Will probably take about 10mins to change,

Heater doesn't blow air? my front windows roll down but my back windows dont. their electric.1988 mercedez 190

Blower is used for either AC or Heater demand. If it doesn't work in heater mode, but work in AC mode then it is a problem with the Climate Control. If it doesn't work in both cases, then check the fuse near the front fender on driver side ( It is not in the fuse box). If the fuse is good, then it is not necessary the blower is burnt, but the blower regulator is burnt. The Blower regulator is underneath of the blower. It can be accessed from the engine side under the wiper motor.

Heater\AC no air in front 05 suburban

ase mechanic:

Sounds like a problem with the front blower motor. there is a blower motor resistor for the front blower motor that controls the speed of the blower and tends to go bad or fry out the blower motor. thats the most likely scenerio since you stated the control head was lighting up and responded to button changes.
