Mercedes: power windows dont work 1986 300E, electrical problems, power windows

Question
I have a 1986 300e and all four windows do not roll up.  They were able to roll down, but not up.  I checked the fuse and it is fine.  Could it be all four window motors?  Thanks for any assistance.  Ken Hinds

You have a W124 Sedan.

Answer:
There are two possible issues = no power and/or bad switch contacts.

Electrical problems or gremlins
