This car has so many problems the window is just the icing. The brake light doesn't go away and no one seems to know what is the problem. The window doesn't want to go up. The car makes a humming noise when it's off. How can I fix all this without paying an arm and a leg.
Windows wouldn't go up or down without pressing switch hard in different directions...replaced great!
At first there was just a hesitation then, one day (raining cats and dogs kind of day, of course!) it failed completely.
Driver's side window would not roll up. Power window switch had to be replaced. I got one off ebay for under $50, and my husband replaced it himself. No further problems since.
just got this 2001 ML, previous owner did not tell me that theres a problem on the master switch. I Did called the dealer gave me $279 for the parts. got them and change, now works better.
My windows will not roll up or down and my door locks to up and down repeatedly after using my remote key and after locking the doors from inside the car. My backseat right door will not lock at all
Actually a 1998, for a few months, window would be difficult to get back up but would always go after messing around with it. Now it is totally unresponsive
