SOURCE: How do I replace a Heater Blower motor in a 2003 Pontiac Vibe?

Remove the Glove box. You will then have access to the Blower unit. There are 3 screws that are holding the blow unit in place. You will need a Phillips screw driver and a 1/4 socket. Once you have located the unit remove the 3 screws and the unit will fall straight down. Unplug the wire harness and then reinsert the new Blower Motor. If you purchase an original GM part this makes life much easier, you just screw the 3 screws back into the holes and then plug the wire harness back in and reinstall the glove box. If you use an aftermaket part you will need to do some wire splicing to make it work but it is a 10 to 20 minute job depending on which part you decide to replace the Blower with.

You most likely need to replace the ignition switch. Sounds weird, but check out other posts. It works.

My 97 bonniville Pontiac heater was working fine then go back in car turned on 3 lines showed in my heater display pushed all buttons and wont come on


Try checking if you have any bad fuses. If good, continue checking power to the switch, if good, continue to check if you are getting power to the heater motor it self.

Heater,air conditioner blower doesn't work


Does it work if you tap it with it switched on? If so, then you have a worn out motor, and need to replace it.

Check power to the motor. If you have power, then replace the motor.

If you don't have power, then check the switch mechanism.

Verify you have good power and ground at the blower motor if so replace and make sure the wires are not routed near the blower motor.

Keep us updated.

What can cause my heater fan on my 1998 Bonniville to turn on and off when it feels like


It sounds like you have a bad connection.I fixed a heater fan on a Grand Am that had the same problem a couple of months ago and it was a bad connection for the ground side of the blower motor circuit.I hope this helps.

I have a problem with my fan on my 1999 sunfire


This is sometimes caused by the blower motor resistor. It is usually an inexpensive repair. The resistor mounts in the heater box, and depending on the location of the heater box, is fairly easy to change.

1999 pontiac grand am exaust smell


If your blower motor is in the engine compartment, I suspect you did not get a good seal around the housing when you reinstalled it. Usually a foam gasket.
For now, push the recirc button so you are drawing air from inside the car into you heater system. Recirc doesn't work on defrost or floor/defrost.

1999 heater fan


The Blower motor (heater fan) is under the dash on the passenger side of the car. there is a panel that has to be removed to get at the fan and can be removed with a small pry bar and patience. before the fan gets removed, check the fuses first, also check the motor by disconnecting the wires going to it and putting power directly to it (this will take some small wires to do). By doing all of this, you will determine if the blower motor is actually the problem. if the fan works when it has direct power, then the problem is someplace else.
