The window motor draws more current as it tries to keep lowering the now fully down window further. There is no sensor that determines the window is already down to cut the power to the motor even if you keep pressing the switch. If you keep your finger on the button or if your buttom jams you will eventually start to melt the switch, the wiring, and perhaps damage the motors, until the fuse blows. Since that fuse is rated for at least 2 motors plus other items (too lazy to look it up - sorry)you could draw a lot of current through the system before the fuse finally blows, so don't count on that to prevent damage. -----Original Message----- From: dmcnews@xxxxxxxxxxxxxxx on behalf of daviddelorean Sent: Sat 2/9/2008 9:22 AM To: dmcnews@xxxxxxxxxxxxxxx Subject: [DML] holding buttons - effect on electrical system Why is it that when you continue to hold your electric window buttons after the windows are in position, the volts drops sharply and the headlights get dim. This isn't just on DMCs but all cars.
