Rear window defroster motor rebuild
 

My rear window motor just barely turns. Who would you send it to for a rebuild? Thanks, Mike

Take the squirrel cage off and put some light weight oil down the shaft. The top bearings get dirt in them .

X2 on that. Guy I work for has a 69 L89 and the rear defroster would blow the fuse instantly, took defroster off and it was super stiff, took the squirrel cage off and used some WD 40 to free up the top and bottom bsgs. Then relubed with some light oil ,worked perfect after.

Hi , another thing to do is check your voltage & ground at the motor & voltage in & out of the switch....
