Elantra power windows work from door switches but fail from main
My Hyundai Elantra's power windows operate well from door individual switches, but do not respond to the main switch (sometimes they move half an inch or just make a click).
The wiring of the driver's door looks new, and the connector is well conected to the main power windows switch.
Re: Elantra power windows work from door switches but...
It was very srange, but all the contacts inside the switches of the main power window console (mounted in driver's door) were covered with soot.
I have disassembled the switch and cleaned the contacts. All functions well now.
The problem occured on a car that is used very rarely, that was most probably the reason of the sudden failure of the system.
Replacement of the main power windows switch would do the same but I have saved the expense this time. Hope the repair will last until I will sell the car.

The main window switch in drives door is starting to short out, power goes to the switch and from the switch to the window motor, the switch will some times make contact and activate the window motor, it's kinda like a faucet leaking water when it shoulden, the switch is letting elec. go through to the window motor.
at the bottom and top of the switch there are retaining tabs. you can try to pop it out at those points with a flathead screw driver, but it is sometimes easier to just remove the door panel to get it out.
First, check the drivers door to body wiring where it passes between the doors. I'd take the panel off and start from the inside and work your way through the part that travels inside the rubber cover to the car. These are notorious for rotting wires in that area, which will cause a large problem.
If the harness is ok, replace the drivers door power window switch assembly. If the drivers door switches are bad then none of the others will work either. I see this very frequently as well from people who use too much Armour All cleaner, or drive with their window down in the rain and get it wet(smokers usually).
1.Remove the switch from the door trim panel.2.Check for continuity between the terminals. If continuity is not as specified in the table, replace the power window switch.POWER WINDOW MAIN SWITCHWINDOW LOCK SWITCH
Connect the motor terminals directly to battery voltage (12V) and check that the motor operates smoothly. Next, reverse the polarity and check that the motor operates smoothly in the reverse direction. If the operation is abnormal, replace the motor.
