I'm having a problem with the passenger window in my 2003 Z4. The window works fine from the passenger side switch but the driver's side switch makes the window go down whether I press the up or down button and will not come back up from the driver's side switch. When I press the driver's side switch I can hear a clicking noise from the passenger window but it stays in the down position. I've tried all the various window reset methods with no luck. Any ideas?
