So as I thought my wet problems were solved, it seems I am experiencing a intermittant window switch issue. At times, the switchs are inoperative just for the rear windows. And, at times the switches will work but only if partially depressed. If pressed down all the way (auto) the window will stop.

This also happened on my e series when the battery blew. The windows would only work using a partial push. If you tried the full press, the switches would not work. The system reset or something within a week by itself.

Is there a reset for this issue?

Coincidentally, I had my rear window regulator replaced yesterday on the e and sure enough that window switch will not work in auto mode.

How do you reset this window switch issue??

Could be a bad switch module but try resynching the windows by putting each window all the way up then continuing to hold the sawitch for about 30 seconds. Do this for each window. My ML 500 is a very early build and was the first to have the one touch up windows. My problem was that when using the onetouch the window would go all the way up then reverse and go down about an inch. MB came out with a new switch module that had new sftware that eliminated the problem. Mine has been fine since the new module was installed
