Here's how to test and repair power windowshttp://www.ricksfreeautorepairadvice.com/repair-topics/window-power-repair/replace-a-power-window-regulator
my power windows quit working, both driver and passanger door switches dont work. i tested all fuses and they work. i think its a power window relay. please help! my windows are stuck down ;-(
Check fuses Might be a bad ignition switch
Loose connection, intermittent short.
You dont, you replace them.
on the driver door take the door panel off. and behind it there is a little black bow with cords running to it that is what you need to change the black box. then your windows will work again.
both my rear power windows does not work in my 2002 ford explorer, why?
I dont know, LOL
On a laptop with battery power it will work.
There may be a fuse blown if the power vent windows don't work on a 1999 Dodge Caravan. If the problem isn't the fuse, the motor in the power windows may need to be replaced.
Get them fixed.
Allright with a voltimitter check your switchs so when you roll them up or down you have power to the switch if not its your door switch. if you do have power check if you have power to your motor. there is no relay switch theres only fuses.
