2000 chevy Venture Power Window PROBLEM

Motor was cheap (free). I do not know how to use a "millimeter", but do know how
to use a multimeter, which by the way lead to switch or motor and since motor
was free that is the first thing I did. Switch is $74.00. But I would still like
to know if there is another circuit relay besides the one in the switch.

Well a partial answer to my own question. Turns out the motor was bad. I found a
melted wire when I took it apart. I also took the switch assy apart and found a
bad spot on the board. I do not have the proper equipment to determine exactly
what is wrong with the board, but a friend of mine does. So when I go to get a
new switch in the morning (ok afternoon got to get some sleep) I will drop the
old one off just to see what is wrong. I would love to know what caused what.
Also I did not find any other relays which some what surprised me. It probably
should not since the gods that be that created this vehicle did not even put in
an on/off switch for the headlights when they are on at night.

Sometimes pressing in the Parking Brake just enough to turn the dash "idiot"
light on will turn out the auto headlights.

I ended up putting in a toggle switch. Works great and I do not have guns being
pointed at me when I go on a military base at night.

The problem was probably the motor starting to short out which caused
the current draw to increase which burned out the switch. The motor
itself has nothing in it to raise/lower the window. That is done by a
simple reversing of the polarity from the switch. Same thing with the
door locks.
