there is an electrical switch on the lock cylinder on many of these. unfortunately, you need to remove the inner panel to access it which in some cases is not all that easy. if you have the guts, remove the panel and check on the back side of the cylinder to see if the switch is still in place if it is check it for continuity across the 2 terminals with an ohmmeter. with the switch in the "on" or "window open" position, ther should be close to zero ohms resistance.
Check your window lock switch.
You installed the switch wrong.
the motor and the switch both work but the window will not move
how do you know its the switch? does the window (power) move up & down? You can use the other switch from the right or left hand side of the one that works. switch the wires. if the windows work, then its the switch. if the switch doesn't work, then its the window motor.
if the passenger windows works than your motor went out inside of your left window assembly, or your button doesnt work anymore
If the drivers side window works; yet, the other three do not check the window lock by the window controls on the drivers door. If it is pressed it will lock the other three windows no matter where you try to roll them down from. If this button has not been pressed I would suspect that the switch is bad or there is a loose connection inside the door panel.
If it is all both windows from both switches look to a fuse, if the window works from one switch and not the other I would suspect the switch. The switch seems to be a weak point on these vans.
If the passenger side works fine and there is no power at the driver side motor, I would suspect the switch. A weak motor will overheat the switch causing it to melt inside where the contacts are.
its either a fuse, or the turn signal switch needs to be replaced
First, check to see if you hear anything when you try the window switch, if nothing and the other window works probably the window switch. Could also be the motor but try the switch first, it's a lot cheaper.
Not really! Have you tried unhooking the negative battery cable? If it then works for a few minutes, it is a sensor inside the door! I am working on a bypass for this common problem! A toggle switch for the window RELAY.
If it won't work from either switch suspect motor or regulator, if it works from one switch then it is most likely the switch.
