Rear window won't roll up

[bigcountry66]

I have an 80 Bronco,  last summer I rolled down the window and took the top off.  When it came time to put the top back on for the winter the rear window would not roll up.  Before this I have used the window for 2 years with out any problems.  Is there any information that might help me figure out why it won't roll up.  How would I test if it's the wiring, the motor, or the key switch?  Thank you.

Big Country,

could be the motor (95% always the problem)

could also be the "mercury switch" which won;t allow the window to roll up when the tailgate is down (this could be malfunctioning)

does the dashboard switch and the key hole not work?
