Kia Sorento power window not working

I had a problem with the power window switch on a Kia Sorento. This solution may work for any other car as well. Many problems can cause the symptom described below.

The window would work if I controlled it from the driver door but not from the button on the passenger door. The issue in my case was that the contacts for the switch were dirty and worked properly after being cleaned. The same problem may happen if a switch gets wet for any reason. After the car was retinted I had to open the switches to let them dry out because the cleaning liquid used to remove the old tint dripped into the switches.


The method to access the switch is similar for most cars. The piece of trim that the switch sits in can be popped out usually. Other pieces of trim may have to be taken out first like I had to do.


The switch assembly comes out of the trim. The driver switches are all on one assembly. A small flat head was used to pry the switch assembly off the trim. The switch has notches on all sides to keep it in place.


The switch is basically 3 layers. The screwdriver was used to carefully separate them. The top layer is a cover which is what you press and pull to control the window. The middle layer is mostly electronics. There are tiny parts involved so you should work on a large flat surface where any parts that fall can be found easily.


 The bottom layer has 2 contacts for the main power used to drive the window motor. Over time the contacts become dirty and no longer close.  In this particular switch the 2 thin flaps get pressed down to meet the round pads to close the circuit. Dust and dirt accumulates here as well as the contacts wear away over time.


I used a scrap cloth  and a flat head screwdriver to wipe the contacts clean. The parts were reassembled and the window is once again working properly. There are many other problem that can cause the same issue but this worked for me.
