On my 2007 buick rendezvous, my blower quit working

The blower motor is behind the glove box, sit in the passenger side seat and kick behind the glove box a few times real hard with your heat on high, the motor might kick back on, I had a Buick and the same thing happened

Repair manual

This is probably the control switch. You can pull the blower motor out an bench test it with a 12 volt source just to check it. I would bet it still works just fine but the switch is fried.

1 thru 4 on my blower quit working , with 5 the only setting working , then the ac went out, then 5 quit working a few days later. it just quit working while it was on. what could this be?

This is caused by the blower resistor. Under the passenger dash, behind the glove box. Drop the blower motor, 3 screws and 1 electrical plug. Behind that is the blower resistor module. Cost me $31 for a new one and took about 1/2 hour to change.

I jump my fan it works fine i change the fan switch still the fine is not working i even check the fuse thats ok

Hello koral_farver,

One common problem that fits your description is a bad blower motor resistor.

Below i will include an image of the location of the blower motor, removal and installation instructions.

The blower motor resister is under the dashboard behind the glove box.

1. Remove the glove box.

2. Disconnect the connector labeled 2

3. Remove screw labeled 3.

4. Remove the resistor labeled 1.

5. To install reverse order.

With what you have done so far by jumping the fan, installing a new switch and checking the fuses this will but you back in business.

The fan for for heater and air is not working!

This is the blower behind the dash or behind the glove box , be sure to check the fuses if fuses are ok then the motor for the blower is damaged and needs replaced, the blower moter is attached to the fan. If you replace the blower motor you will need to get its location via vehicle specific. Do this on the web.
