Default Heater Blower Motor

The heater blower motor sounds like a b52 taking off when its running. I can only assume the barings are going on the blower motor.
So where is it and do I access it from the engine side or the glove box?
How do I change it out. I know my GM dealer want big bicks for a new fan motor and install. I hoped I could find the blower motor and install myself.
Thanks all for you suggestions in advance.

Have you checked the cabin air filter area It may have some debris in there that have found their way to the blower motor,

EVERY time that we have come across this issue, there was some debris caught in the blower fan. I would fish around in there one more time to make sure, I would put money on that being your problem.

also take account of the papers that you have in your glove box. I've seen some GM vehicles that "suck" the papers right out of the glovebox and into the climate control.

If you have a powerful Shop Vac take out the cabin filter and try using the Shop Vac with the long thin rectangular wand pushed as far into the cabin filter opening as possible. You might get lucky!

When you had the cover off and the cabin filter out did you look into the blower area with a flashlight-preferably when it'* dusk or dark outside the car? If you do see something use one of the flexible tools with wires at the end that you can clamp onto something to grip it to pull it out. Or you can take the blower motor out.

I'm voting with the person suspecting something from the glovebox found it'* way into there.

If you do need to pull the motor due to it being bad, or simply to clean things out...this is the procedure.

7. Disconnect the electrical connector from the blower motor.

9. Lower the blower motor and rotate counter clockwise to remove from the vehicle.

It'll be worth the effort to really check the fan for debris. I didn't see anything the first time I looked. After reading forums, I took a better look and found several small leaves and pine needles. It sounded awful!

More at this thread... http://www.bonnevilleclub.com/forum/...ic.php?t=66567 and a couple pictures.

Default Your guys are good.

Many thanks to you all. I looked harder with the flashlight and found a piece of old filter media rolling around in there. Now its quiet again and I saved the money and time of pulling out the fan motor to find something as small as that. bet the dealership would have changed the motor anyway and charged me mega bucks.
This is the reason i read this site everyday.
Thanks again all and happy holidays...................
