Hello,
2009 Santa Fe. The passenger window would only go up from the driver's side switch, not down.
The new switch module I bought enables the passenger window to operate normally from the driver's side, BUT, now the driver's side won't work at all. It did previously work fine.
I moved the wires around while pushing the button and nothing worked.
So, I know that both window motors work, but can anyone guess what might be going on?


Thanks!

 

What you need to do is,
with a voltmeter, check for power coming out of the switch and see if it is getting to the selected door. If not ,may be a window control module involved or open wire.
