Can anyone give me advice on how to lower the running board manually so that I can access the mounting bolts? The passenger side motor is seized and its stuck in the closed position and I cannot access the mounting bolts.

 

Im sure someone else may have more details but I just had mine apart and without actually doing it myself, and depending on why it was seized I would trying the following:
1. Unplug the motor from the vehicle.
2. Unscrew the three phillips screws holding the motor cover on, be careful not to strip the screw heads.
3. Pull the motor cover off. There are some big magnets in there so pull and twist with as much effort as you can. (this may be very difficult from under the vehicle, or maybe not)
4. If your gears are not stuck, you should be able to turn the motor and it will slowly lower.

If you gears are seized, im not sure what to do?
