Well, after 11 years and over 200K miles, plus near-constant running in SoCal weather, my heater motor is making "rumbling" noises. At first I thought it might be just a leaf stuck in the blower, but it's sounding more and more like bad bearings. How big of a job is this to change? (Please don't tell me I need to disassemble the entire dash .)

 

All you have to do is unplug it, then remove the 3 screws that hold it in

 

Thanks for the reply. I found it and it almost looks TOO simple! I guess I'm used to working on BMWs, where the heater motor would likely be buried deep inside the dash.
