I don't know if anyone ever fixed this problem but I am going to show how to fix it anyway. First take the switches off the door...duh, then carefully pry the rocker part off (do not pry off the window lock rocker) like this ---->
Next take the top of the switch off and you should see this, notice the tiny leds.
Next carefully pry up on the pcb with a screwdriver here ----->
The problem is not with the leds, but the bad solder joints on the resistors, here---->
Resolder the resistors in the pic above to look like this ---->
Also resolder any leds that look like they may have bad connections or just resolder everything just to be sure. Now bend the metal thingies back so the pcb will fit back on and then spred the metal thingies back out to hold the pcb again.
Your lights should look like this now.
Not like this--->
I hope this helps and I hop that there is not already a post about this I did search but did not find one.
