67 GP Rear Passenger Power Window INOP. How do I get into the window components?
 

Rear passenger window stopped working. When I use the window switch from the driver's' control the car's voltage drops but no window movement. How do I tear down the car to get to the rear window components?

With HT you have to remove rear seat first to access the side interior panels for removal

Did you check the local switch (right rear) as well? Are both not working?

The car is a HT and the local switch is not working.

First thing I’d do is pop out the local switch and test it for power (key in run or acc). First see if power is coming to the switch and if yes then check for power leaving the switch when the switch is applied for up and down.

If the switch is getting power and working properly then pull the backseat, armrest and inner door panel to assess the mechanism.

Since you say it’s drawing power it’s probably binding somewhere in the mechanism, maybe a broken roller or guide? Should be evident.
