Rear power windows

[Toukis]

I have  1982 Buick riviera convertible how do we remove rear windows any help or advise would be very much appreciated.can hear the motor working but windows not moving

I think I remember from my 84 that the mechanism contains a perforated nylon tape that can dry out and crack apart leaving the motor to spin with no operation. I took it to a glass shop back in that day and they had a roll of the tape and fabricated a fix.  Dale

Remove lower seat cushion.  Top down. loosen rear interior panel (no need to remove just loosen the top for access)  Remove the two nuts on the top and get a very long extension (I welded a socket to a long pipe) to get the single bolt on the bottom.  When the three bolts are out the whole assembly with glass, motor, and frame will lift from the top.  Probably the nylon tape you can still get replacements as it was used in many different Manufactures for a while.

Where are the bolts on the rear lower cushion

Yes...the correct nylon tape replacement is still out there. The "HELP" products found on a "tree display stand" at many auto parts stores, including NAPA, used to include this power window tape. Don't know if that's still the case. John
