My '80 Corvette needs a passenger window regulator gear replacement. The
motor works fine but
the teeth on the high side of the regulator gear are worn down.
I have the 1980 Corvette shop manual but it's not really very instructive on
precisely how the regulator is removed.
After telling me to remove the door panel and the inner door panel access
cover, it then tells me to do the following:
1) Disengage wire harness at motor.
2) Remove inner panel cam.
3) Punch out window regulator rivet center pins, then drill out rivets with
6mm (1/4") drill bit.
4) Disengage regulator rollers from sash channel cam and remove regulator
I've got no problem getting to Step 2 above but I don't know what or where
the inner panel cam is. There are no pictures in the manual.
Since this isn't the first window job the door has had, the rivet removal in
Step 3 has already been done. There are two nuts left there to remove. No
In Step 4, I can grope around inside the door and find the 3 regulator
rollers in the sash
channels, but I don't have a clue as to how they're removed without removing
the sash channels.
And lastly, while it doesn't actually say so, I assume the motor and
regulator come out as an assembly.
I'd really appreciate any help anyone could give me on this. As I recall, I
spend close to $500 for a power window repair in the shop.
