happens all the time. Pull master switch and clean the contacts for the switches. I mean the actual contacts under the switches you push up and down. Very common. If that doesn't work replace master.

So it's master switch you clean not the passenger?? Because the passenger switch gets its power separate from the master though its ground goes through the master.. Hmm I have cleaned the crap out the passenger switch and I just ordered a new one.. Though I guess I'll try cleaning the master now as well.

It's common I have been hot wiring my motor to make the window go up..

 

[kamikazemkiii]

could it be the switch that controls the window?
or the window motor

there both individual you could have the master switch roll up the the pass and the pass not roll up the drivers. and vise versa.

I had a problem like this, for me it was the electrical connector located behind the passenger side kick panel. It carries power for the window motor and it had worked itself loose.

Again, 99% of all window up/down related problems are the master switch.

The passenger switch will not work MOST of the time if the master switch doesn't.

A motor is a motor, if it works one way, it will work the other.

Clean the contacts +1!

Well my motor most defiantly works.. Better clean the master switch.

Oh and if you just want to test to see if your motor is bad from the passenger side switch connector

Step 1 -- Just get two pieces of wire.. one piece about 4 inches, and the other about 2 1/2 Feet long in length..

Step 2 -- Strip the shielding from the ends of the wires..

Step 3 -- Lets identify the wires. (You must already have the passenger side window switch wire connector unplugged) Looking at the wiring connector for the passenger side switch you will notice the following wires.. BLUE, RED, Green/Yellow, Blue/Yellow, and finally a Blue/Black wire.
The wires you need be concerned with are these 3 wires:
BLUE = Power wire (key must be in the on position)
RED = Makes the window go up when 12 volt power is applied..
Green/Yellow = The other wire going to the window motor. (you'll ground this wire when making the window go up)

Step 4 -- Lets check to see if the motor works by rolling up the window..
Take the smaller 4 inch wire from earlier and insert one end in the Window switch harness to the RED wire and the other to the BLUE wire. Next attach one end of the longer wire to the GREEN/YELLOW wire (CAUTION:: THE GREEN/YELLOW wire is extremely close to the BLUE Power wire YOU WILL GROUND OUT THE POWER IF THEY TOUCH while conducting this test) then put the ignition key to the on position and touch the other end of your longer wire to a ground.. i.e. the seat rail bolt.
The window should roll up.
If you want to make the window go down reverse the power and ground wires.
