2009 ML350 Rear SAM - Rear windows stuck down
Rear SAM got wet so I took it apart and cleaned corrosion with a toothbrush and alcohol. All of the issues fixed themselves after that except the rear windows are still down. I cleared all fault codes with icarsoft scanner and went to live data for Rear windows. It tells me when I'm pushing the button to put rear windows up in live data so does that mean that the switches are still good? Does that mean that the SAM is not the cause of them not working? I'm really trying to troubleshoot the issue myself Rather than take it to a Mercedes dealer because I can't afford them.

Any help you can give me would be greatly appreciated

And what were the codes that you deleted?

When you cleaned the rear SAM, did you remove both black plastic covers and clean both sides of the board?

I cleaned both sides. I'll check what the codes were. They might have said open circuit. But what's interesting is when I go to live data on my icarsoft scanner, it recognizes when I hit the up or down button on rear windows. It says "window up/ down" when I hit the corresponding button. I don't know if that info helps you at all. Additionally, there is no sound that comes from window or anything when I push up or down buttons

I'm not being funny, but you've not got the lock-out engaged on the drivers panel?

Ha! No worries! Do the windows work from the drivers controller?
