Windows and outside mirros dead . Help!
Have a 2005 ML500. If the key is in the acc position the windows (all 4) and outside mirrors work fine. When you start the engine the windows and mirrors work for about a minute and then they are dead. turn off the engine and turn the key to acc and everything works fine again. Voltage is 14V at fuse 25 the entire time the engine is running, power is constant. Trying to figure out why my windows wont work if I have power continuously at the window fuses and how it is related to whether the engine is running or not. I disconnected the battery for 5- 10 minutes to do a computer reset and also cleaned ground connections. Maybe a master window switch is going bad ? Need to figure out what to check next.
