2004 Kia Optima Repair Question
Rear window switches cannot control the back windows.
Thing Determined so far:
-All windows work
-Master switch works
-Window lock is not on or stuck on
-All switches work
-Master switch can be interrupted by the windows respective switch
Thank you in advance
it sounds like either a wiring issue or both the rear motors are bad. test each motor separately, if they work you have wiring issues, if they dont, remove the panels and inspect the wiring before condemning the motor.

Most likely a fault with the master switch.
This is rather complicated to explain so I don't know if I can get the message through.
When the master switch for the respective door is not providing continuity in the rest position, the rear switches would not work. Likewise it can also be the reverse condition.
When using the master switch to control, you are able to get the windows moving because the switch is being turned to open and close some connections therefore you have no problem.
