OK, got some work done on this last night. The method of troubleshooting which I'm going to do is to start with the least evasive first. Meaning that I'm going to remove everything before attempting to take the motor assembly apart. The problem with this motor was it would go left to right but not up and down. Feeling the motor with your hand while using the joy-stick control on the center console resulted in the motor would make a Clicking type noise when trying to get the motor to go up or down. Upon visual inspection, the screw threads had so much crud that prehaps it was causing the mechanism to bind.
The below pics show the screw threads move up and down by a plastic thread in the switch drive housing. This needs to be cleaned up before doing any trouble-shooting. This can be done in a few ways but a cleaning agent like Kroil and compressed air. PS these where much dirtier prior to taking these pics.
