No power to passenger window
***I have done extensive searching on this issue, and I have not been able to find this condition/answer to said condition***
2009 Mazda CX7 GT
NO power to passenger window.
The lights on the switch AREN'T illuminated
Drivers side will not operate the window
Passenger side will not operate the window
No issues with the other three windows or moon roof.
Anyone have any suggestions? The Re-initialization/reset won't work, due to the fact the window is completely inoperable. I have changed the 15a fuse interior, as well as the 20a and 30a in the engine bay.

The driver's side switch is illuminated, but the passenger side is not. There are no noises when either switches are operated. It would appear that power isn't being supplied to the switch as well as the motor.

A funny little thing can happen
This is a ford/Mazda thing with the power window. Passenger side. You'll have full power to the switch. Motor and wiring through the passenger side. What happens sometimes or if your battery gets disconnected. Or a surge or whatever. There's a relay built into the drivers side switch. It'll fault out the pass. Window. Start the car. Roll the window down with the passenger control. Hold down on the Sievers side control on the passenger button till you hear a click then pull up on the drivers side passenger button. It'll reset the relay. Could be what your missing. It's on Google. Can't remember 100 percent what button devs/passng to hit all the time
Had to do it twice in the past myself
