Looking for a working power window relay for a 68 Cutlass Supreme. My left side front and rear open fine, the right side does not move at all but I sometimes can get the front to very slowly roll down and up but then it dies out and I have to assist/force it back closed. Been that way since I got the car. Lets try changing that relay.

 

Sounds like you need to check the motors/guides/tracks on the right side.
Most likely, they were never greased and the old grease has dried out.

Can you hot wire/directly wire the motor on the right side door to see if it works?

I have a bunch of relays...they hardly ever go bad....let me know what you find out.

 

If the relay was bad, all of your windows will act the same, as the relay controls all of them...

 

Hey guys thanks for posting here. I actually made a thread about this in the electric section with photos if you guys want to chime in that would be great. Theres more info on the issue there.
