I have a 1984 Cutlass Supreme 4DR with powered rear door butterfly windows. The driver side rear window butterfly does not work and I need a new motor. Any info will be appreciated as to where to get a motor and also if the motor is the same as used in front doors.

 

did you try taking the motor apart ?

many times the brushes wear out or get gummed up and a good cleaning will have you up and running again

 

Thanks for the reply. I did not think the motor was repairable but I will try your suggestion.

 

 

As you suggested, I took the motor apart and cleaned/lubricated it. It now works OK. Thanks for your help RetroRanger.

 

Good to know thanks for posting back.

I have "saved" a ton of stuff like that over the years by just taking it apart first
