Re: [DML] Re: Electrical problem

You have a ground loop somewhere.

The window switches provide the grounds for the power 
windows.  Lets number the connectors on the window
motor 1 and 2.  When the window switch is not pressed,
no connections are made to connectors 1 and 2 - they 
both float.  When you press the window switch down, the 
switch applies power to connector 1 and ground to 
connector 2 and the motor moves in one direction.
When you press the switch up, the switch applies
power to connector 2 and ground to connector 1, 
and the motor moves in the opposite direction.  The 
window motors should not be grounded to the door
at any time.

Note that all of the current for the window motor is 
flowing through the switch.  This may be where your
switch problem started.
