left rear window stuck down, "92 600sel"

[mmaeser]

It's only 107* here in Phoenix, and my left rear window is stuck in the down position! My rear fuses in the trunk are all good. When i push either of the switches, it sounds and looks like the window wants to go both up and down, but it will not continue upwards. any good ideas on servicing this, and parts that are required? thanks, mike in phoenix. Also my left rear door will not suck closed like it is supposed to, but i can hear the vacum in the door working. Any ideas? thx.
