I have a '94 convertible that had the same problem -- the window would not
drop then raise again when the door was opened.
The problem was a switch inside the door latch on the offending door.
You can test the door latch with a ratchet extension or other suitible
object to simulate the post that the latch strikes. Open the door, then use
the ratchet extension to "close" the door against. (You might be able to do
this with your finger, but I found that using a tool was the way to go.)
Anyhow, raise the window to the top and operate the handle to open the
door -- the window should drop about 10mm (it should drop, and I think it
goes 10mm, but if it drops at all it drops as far as it should).
Then, using the tool, "close" the door (set the latch as it would be if it
was grabbing the post), and the window should raise.
My guess is that the window will not drop, and therefore it won't raise
either because it's already at the top. In any case, fiddle with the door
latch -- cause it to overtravel a little -- and this should activate the
window movement. When you "open" the door, I think you can mess with the
latching mechanism a little, and cause the window to move too. If you can
fiddle with the latching mechanism and cause the window to drop and raise
properly, then there is a switch inside the mechanism that has a sticky
If you are good at investigating this sort of thing, you will find the
switch and be able to clean the linkage. The trouble in my case was not the
window or the switch itself, but was the linkage between the switch and the
latching mechanism. The linkage operates on one plane to move a part on
another plane, and this change in direction (planes of operation) and the
pivots needed to support such a design is where the problem is. You can use
a shot of contact cleaner followed by a suitable lubricant to free the
sticky linkage parts. I messed with thinking the linkage was bent or worn,
and played with the idea of reforming it, then it hit me that it was just
sticking due to years of corrosion. I dropped some sewing machine oil on the
pivot, and viola! There is a small spring that plays an important role in
this problem, and the corrosion on the pivot overpowered the spring,
affecting the operation of the switch. By operating the latching mechanism
with your finger, or tool, you move the mechanism past the point where it
moves by itself and this helps the spring operate the switch.
The latch mechanism does a good job of hiding in the door. The door panel
has to come off, and there are screws that come out from the inside. I have
a Robert Bentley Manual for my E36, and it helped alot to get the latch out.
I fixed my car, maybe yoru question would be betyter asked to the original
The fuse controls the entire window operation, not just the part of the
operation that happens when the door is opened or closed AND the window is
8) tried and tested ur suggestion and worked thanks for information

Thanks for the update. Glad I could help.
It was the little pivot thingie, wasn't it?
I fussed with mine for quite a while until I realized that the parts moving
on the verticle path were not moving the parts on the horizontal path, and
the trouble was all in the wrist. I think I eventually took the little
spring out and cleaned the post, and it has worked ever since.
