2013 Hyundai Tuscon window problems
 

Started with passenger window could only be controlled from driver side, then progressed with passenger window could not be moved at all. Check 3 fused under dash, checked fuse in engine compartment, changed motor on passenger door, changed switch on driver door.
With new switch -> driver does not work, other 3 windows work fine
With old switch -> drive window works fine, other 3 windows only move down.

Currently working on checking power/continuity to motor plug on driver door. Running out of options.

Sounds like a faulty new switch???

The way the system is wired all the wiring from all the switches has to be a complete circuit or certain parts will not work.
If after you replace the switch again and if it still doesn't work right , start looking for a possible broken wire in the driver's door hinge area. The constant flexing of those wires does eventually cause some to break and separate. It will take someone with some electrical background to find and correct the problem.

The door switch provides two ground connections for the master switch operation, and the master switch provides two ground connections for the door switch operation, one for up and one down. A faulty door switch may result in the master switch actuation to fail. Example: Rear passenger door switch can open and close the rear passenger window. The master opens the same window but fails to close it. The master switch is good, but the rear passenger door switch is failing to provide a ground path for the Master switch up circuit.

The only way to really diagnose this system is with a schematic diagram. With that AND a multimeter you need to verify the grounds are available in each switch at the proper time.

If the window motors work at all that would rule out the motors.
Most times it is defective switches.

I am having the exact same issue with 2013 Tuscon. Old switch Driver window works fine but other windows are down only (but they do come up fro the individual switches). Changed out with a new switch and other 3 windows work correctly, but driver window does not work at all. What was the outcome of your situation and did you ever find what caused it?
