Car power window problem

Does any one know an easy way to test the components to the power windows. Like the switches or relays or even the motor. This isnt for my truck it is actualy for my wifes car.

This is my problem, I have 1 window that doesn't go up or down at all, then i have another one that goes up really slow.

I am fairly certain that the 1 that is really slow is probably the motor but the other one I'm not really sure on what to test first.

I'm sure power windows aren't that hard to to work on. I tried to do a search but couldnt get that to work, too hi of a load or something like that. Any help would be great, Thanks.

you could try to jump the window motor here's how you can do that. first get a battery jumper or a good battery and some wire. kinda like speaker wire or something like that. However the best thing to use is a good set of testing leed wires but speaker wire should work. Take the door panel of the door so you can get to the motor and unplug the connector. Then put the one wire to the possitve cable of the batt. jumper and 1 to the negative cable. Just try to put the wires to the terminals on the motor. if the motor is good it will operate. if not then it wont move the window.

make sure u dont have a button on the drivers door that locks out the other windows, this was a safety feature on some models. if that button is sticking or possibly dirty, it could be causing your problem. good luck

If you have one stuck down, it might be jamed. You can loosen the motor bolts to free it up. When they get old they can go past the stop and get twisted and won't move.

I know it isnt that lock button because the other windows will go up and down. The front passenger side window goes down very slowly and really shakey and the back passenger side doesn't go down at all. The car is a 97 so i shoulds think that it wouldnt be that old. What should i look for if it is jammed shut.

paredneck's check will work to test the motor, but it's my experience that the tracks wear out before the motor ever does. Here's a few ideas to get you wrenching...
1. Try to jump the motor like Parednecks idea, it shouldn't hurt anything, and it will let you knoe if you have a mechanical or electrical problem here. If jumping it works, then
2. (on the one that dosent' work at all) use a test light or a multitester (you can pick one up at a hardware store for less than ten bucks, and test for 12 volts of current through the circuits when the window switch is depressed. If it's a short you should be able to find it this way, it's jsut going to take some time.
3. if jumping it dosen't work, then you have a mechanical problem. This is all to common on power windows I'm afraid. your should have two tracks that the window rides in, and one that lifts it, with a roller assembly of sorts that raises and lowers the window. If the roller is off track then that will make it jam, so inspect the roller and the track to see if there's any abnormal wear and tear ( deformation of the track metal, bent axle of the roller, messed up roller, that sort of thing) I think that you are going to find your problems here, because you mentioned the other one that is slow. A slow window points to low voltage (rare) a messed up motor (also rare) or some overworn mechanism ( pretty common)
4. parts for the car might be found at a junk lot, I'm not sure if the chains carry this type of stuff, and I would try to stay away from the dealer if at all possible.
5. Hope this helps and happy wrenching
(oh by the way this is from a repair I did of a 97 toyota sedan I helped a buddy fix, similar symptoms to what you are saying)
