Default 2005 GXP Blower Motor dead

2005 GXP 62,000 miles

I actually figured out my problem, but thought I'd share some info and pictures.

The fan quit blowing. Checked the fuses. Pulled the cabin filter cover and made sure the fan was free to turn. Then went after the blower.

The blower is relatively easy to get to and remove. I removed the kick panel under the glove box - two screws right under the glove box door.
Unplug two connectors attached to the panel - light and a sensor. Set panel aside.
The motor is right about where your left toe would be.
Unplug the three-wire connector from the motor. (The center wire has +12V).
Twist off the air vent hose.
Remove 3 philips screws from the motor.
Motor drops out. Ready to be replaced.

I wasn't really sure the motor was bad yet, so I took it a little farther and removed the 4 screws holding the plastic cover on the motor. Then you can twist and slide the cover off the metal motor housing.
Then I removed the metal cap/bearing which had two philips screws.
Now I could see the problem... both brushes were completely worn out, and look at the armature wear!
(35 minutes from removing the panel to taking the pictures)

Priced out the blower on-line... $130-175. Ouch! If anyone has a better price, tell me!

I have more pictures if anyone is interested.

How to Replace a 2005 Bonneville GXP blower motor
ZeeVert – R Veldman 9/24/2008

At the time of this write-up, replacement motors cost at least $130.

The blower fan is relatively easy to get to and remove.
There are 5 screws and a few wire connectors.
With a few tools, you can have it out in about 15-20 minutes.
This car is a GXP. Your Bonneville or other GM may be similar.

My recommended tools:
Small screwdriver (for connector)
¼” ratchet
1” extension
5.5mm socket (or 7/32”)
7.0mm socket (or 9/32”?)

There is a plastic kick panel under the glove box.
Using the 7mm socket, remove the two black screws.
Pull the panel back and down and the Christmas tree retainer will also pop out with the panel.

There are up to two wires connected to the panel,
The small black connector appears to be a temp sensor(?). I used the small screwdriver to help disconnect it.
The larger, blue connector is an interior lamp. Disconnect it with finger.
Set the panel aside.

The motor is located against the firewall, towards the front of the car. If you’re seated in the passenger seat, it’* just above your left toe.
Unplug the 3 wire connector from the motor with finger.
(There are 4 Philips screws in the motor. Don’t bother removing them. It’* just a cover.)
Using the 5.5mm socket, remove the 3 gold screws.
The motor will drop out.
Wiggle and twist the vent hose to remove it from the motor.
Done! (reverse order to install)

Well, I hope that wasn't too much.
If you see an error please reply.
If you can confirm this works for other models and years, please reply.

New fan motor installed (15 min max) and working great (so far).
Note: new motor includes the fan drum.

Thanks for all the cards and calls and good luck with yours.

my 01 bonneville is different u have to take everything out
the fan blade is larger than the opening the motor bolts to!

ive replaced the fan motor 3 times before each time taking 2-3 hours or more cus i cannot maneuver it back in.. as i never figured out the trick ive always managed to pop it in by luck towards the end when im fed up with it. usually while im juggling it to get it back out itl pop into place..


mine has to be removed with the odd large plastic piece that the motor and so on screws to. its hard to explain..... it covers the entire bottom of the compartment the actual fan blades rotate in.

why is mine so different?

107,000 miles. The replacement is still working.
It appears that the GXP system is different than the other Bonnevilles. Different motor number.

I'm Waiting for the Motor to come via UPS. Found it at 1A Auto Parts for 64.95 with free shipping. The dealer wanted 299.00! Looking forward to my fan working again. Thanks for the detail. This looks like a job I can easily handle.

it may not be exactly the same alot of year difference, but most gm'* are similar, its either above the pass side footwell or pass side firewall looking from the outside with the hood up. first take the connector off and turn the fan on make sure its the motor. if your getting power in all steps take the blower out and replace it.
