drivers window inoperative

Drivers Window goes down but only goes up intermitenly. Could this be a cracked circuit board at the switch? Tried to disassemble consol but was unsucessful. Help

Hi there,

I had the same problem with my ML-430. Talked to one of the Mercedes Techs, who informed me that this was happening with many of the M-Class vehicles right around 15,000 -20,000 miles. Once the first window starts to operate like that...the rest follow. It was under warranty so they replaced the switches on all windows. I am now at 60K miles and have had no more problems.

Hope that helps:)
