HI all. I have done a ton of research and still cannot find my fix. I have a 98 ML320 with the standard "driver window won't go up" problem (also the passenger rear window will not work). Took assembly apart, tried bending the contacts, but ended up ordering an entire new switch assembly for $35. Install did not fix the problem. The driver and right rear still don't work. Swapped fuses and relays, still nothing. I assume the two windows work on the same circuit. Any ideas would be great. Thank you!

Relay K18 and fuse #30 control the L/F & R/R windows. Relay K16 and fuse #29 control the R/F & L/R windows.

Switch relays and see if the problem transfers to the other windows.

Maj Duned,

Already tried swapping the fuses and relays as stated in my original post. Think maybe there is a short somewhere? I've covered all my basic fixes of the classic window problem, and still have drivers front and pass rear not working. Just not sure where to go from here. I am also assuming that the two window motors did not simultaneously quit working. Thoughts?
Thank you!

Sorry Maj! My fingers missed the "e" in Dundee!
also, when I swapped those fuses/relays, problem did NOT transfer to other windows.

In your original post you only indicated that you switched relays and fuses but not which ones.

Remove the connectors as indicated in the JPEG and see if the window comes up. The first one is for the L/F and the second is for the R/R.
