here's something i found out ...... if your heater motor resistor is burning out. replace your heater motor..... the bearings get dry and cause more heat in the resistor than it can handle.
i put 2 resistors in mine before i decided something was causing the failure
i removed the blower motor and it was real hard to turn..
funny thing ,it did not make any noise.........

Good advice John...I'm going to pick up a fan just in case,when I replace my heater core.Where did you buy the fan motor from??Maybe would NAPA have them.

napa's units are generic , no connector.
here's the one i bought. http://cgi.ebay.com:80/ebaymotors/ws...m=120306331347

I got mine at a pick & pull. $10 for fan and resistor. 1500s thru 3500s, 94 to 02 are the same, so they are easy to find.

on high speed my fan makes a loud flutter noise but is fairly quiet on lower speeds would this be from bad bearings

It would, mine also screams at me until its been on for a few minutes. There has to be a grease zerk or oil hole somewhere in there....right??

diklohill

maybe , maybe not I will find out , I am going to pull mine off and check it out,

I replaced my HVAC motor just over a year ago. A bunch of folks on here recommended I go with a Bosch from the dealer. The price difference between dealer and aftermarket stores was very small. I think I paid $170 and the aftermarket was $150.
There were no grease zerks on it or anything, I believe it has nylon bushings not bearings.

Does anyone have a part number for the resistor?

I know that a bad motor can take out the resister but not always. Replaced my resister about two years ago still going strong.
