If you will look at the door panel area right in front of where he motor bolts to the window regulator You will see three dimples like would be made by a center punch to mark where to drill. That is exactly what they are for.
Find those dimples and they will line up with three 5/16 bolts that hold the motor to the regulator. Sometimes on the bottom bolt you won't find the mark but you can still see where to drill. It takes a large bit about 3/4 inch for clearance for a socket. Nothing to it after you punch the holes.

Hi,
Did you disconnect the adapter between the switch and the motor and hook a straight positive from the battery and a ground to the door into the adapter on the motor side to make sure it was a bad motor... There are two wires coming from the motor to the adapter, you can't go wrong... The positive can go on either wire, the negative just goes on the opposite wire... what will happen is the motor will turn in one direction, switch the positive and negative and the motor will turn in the opposite direction...
The switches go bad a lot faster than the motor...
What usually causes the switch to go bad is when the mechanics that the motor drives are in bad need of grease for smoother travel and less friction... The switches have to be held too long and it slowly burns them out....
Hope I caught you before pulling the motor...
It's worth checking...
Have a good one,
Terry...

Also you could test the motor with a test light. Operate switch and you will have the light on for one of the two wires for the motor. Operate switch other direction and power will switch to other wire. Probe both cavatives for power with switch held in up and then down. If by chance you find power on both wires at the same time then you will need to look for a broken wire in the circuit. Usually in the area where the wires pass from the door to the cab.

[font size="1" color="#FF0000"]LAST EDITED ON 03-Jul-00 AT 08:08 PM (EST)[/font][p]Hi again,
If you want to check for power at the two wire connector with a test light. You have to get into the interior of the door where you can see the motor and the two wires running from it to the connector and test the connector on the switch side...
If you just pull the switch out, driver or passenger side, both have more than two wires and are quite confusing which wires should be hot and which shouldn't...
Last, if you find there isn't any power to the connector from the switch when the switch is pressed, I would still check the motor with a direct power source to ensure it works before buying my switch(es)...
