Power window issues
Power window issues Today I went for a drive and before I took off I rolled down my windows. The passenger window went about halfway down, then I tried to roll it up and it wouldn't budge. It works fine going down but it's almost as if the button doesn't want to work for it to go back up.
Did some trouble shooting.. Pulled the motor, tested it. It will only turn in one direction and that is down. It also will not work up or down if I try to use the drivers side buttons. So I tried hooking up another motor to it and it will only turn in one direction as well. I figured it was the switch so I purchased a new one and that didn't solve the problem either.
So I'm wondering if I have some sort of wiring issue now. Has anyone had a similar problem to this? Luckily I got the window back up for now but I would like to find a solution for this.

Have you considered that it is probably the motor? You said you tested it and it would only go one way so that should make the diagnosis pretty simple.
You can test this pretty easily. The switches provide power to the motor and just reverse the polarity to make the window go up/down. If you test the voltage at the motor connector, that should confirm pretty quickly if you have a switch problem.
BTW - the driver's side switch is wired through the passenger side switch.

Correction... the passenger's side switch is wired through the driver's side (i.e. all window wiring goes to the driver's door first).
I plugged a brand new motor into the connector and it still would only operate in one direction. So that is why I'm so confused.
Could it possibly be a bad relay or do these cars even have those for the power windows?
I will try checking to see how much power I am getting from the connector that plugs into the motor and see if my issue comes from there.

You probably have a bad switch. These switches are more complex than you'd expect. If you check out a schematic (see shbox) and test the circuits, you should be able to confirm where the problem is.

I will look into shbox.

Its the driver door module / switch. Make sure the connector is fully seated on the drivers side. Or check the wiring.... Some cars have a module separate from the switch also, might need to look into that.
Are you saying its the actual switch that you touch to make the window go up or down, or the switch connector with the little holes in it? I replaced the switch button as stated earlier.
The problem is in the switch module. (Likely not the connector.) You need to test the circuits to figure out if the problem is with the switch on the driver's side or the switch on the passenger side.
If you have a spare switch in-hand, you can move it over to the passenger side and see if that's it. If that doesn't work, you'll need to test the circuits to isolate the problem.

I've moved the connector to both the driver side and passenger and now the window won't move on either one. Very frustrated at this point.
Could it possibly be something in the body control module?
You need an education on the topic - a how-to won't be enough. You could read some books and pick up the skill or I'm sure someone has a series of youtube videos on how to use a multi-meter. That might be a good place to start. Learning how to read the electrical schematics is a little more challenging.

I hope it stays working from here on out, *knocks on wood.
