1977 Mercury Marquis Colony Park

Recommended Posts

I finally received my newest toy, a 1977 Mercury Marquis Colony Park wagon.
She will need a few cosmetic things sorted out but my first project is to repair the tailgate window mechanism.
The glass goes down fine, its the up part that is the issue!
The motor runs and the glass can be pulled up, but its like the motor doesn't have enough torque and once up, the gears back drive.
Access to all of it is near impossible, so this is going to be fun!

Anyone have and slick hints or tricks?conf.gif

I would check the gear teeth on the motor and window mechanism to ensure the teeth are not stripped.  Door window motor mechanisms suffer the same problem, over time those gear teeth just get stripped and worn out or broken causing the window to have problems going up.
