I had this same problem of my keyless entry system just not working. I unplugged the negative battery terminal and now it works, but now my passenger side window control on the drivers side won't work. The passenger window will still roll down from the passenger side control, but the auto is gone. Any suggestions?

 

Are you sure that you earlier had auto mode for your passenger side window? Unless I am mistaken only the driver side window has auto control.

 

yes i am sure. it is written on the passenger side button. Any idea on why my driver side will roll every window down but the front passenger side?
