Blower Motor Has Stopped!!!!

[mwhayes]

I have a 1990 Chev Blazer. The blower motor stopped working. I have replaced the blower motor, the blower motor resistor and the blower motor relay. It still does not work. I am getting power to the motor. The case around the evaporator has a hole in it, I don't know if this has anything to do with it.

PLEASE HELP!!!!!

Thanks

check for a good ground connection. is there alot of rust? with a piece of heavy wire try grounding the blower motor case to a known good ground.

X2 on the ground..........been there, done that

X3. Yep, got to have +12 and ground.
Hole should not stop the fan from running, unless its where the ground used to be hooked up, or it was caused by a foreign object that penetrated the cover and jammed into the fan............

Did you check the blower motor resistor??...it provides the resistance to get the different speeds ,it may have roached the spring coils in the resistor....usually you will still get high speed though if one dies...try putting 12V right from the positive battery terminal to the blower motor after ensuring its grounded good and see if it'll spin then....could be a pencil or drinking straw slid down the defroster duct and jammed the fan wheel,and or blew the fuse too...

Last truck I fixed a dead blower motor on just had a blown fuse--the fan was FULL of dead mice and nest material!!...when I removed the blower motor the entire heater duct under the dash was packed solid with jute padding the mice took from under the carpet...I cleaned ot all out and flushed it with a garden hose and used some Clorox to help disinfect it..I pity whoever has to ride in that truck this winter,it still stank like dead mice pretty badly after it was all back together and working!..
