I just installed a Compustar 9000 yesterday in my 06 TL. I noticed last night that only the drivers door window button lights up at night but all the other window buttons are not illuminated and the same on each door. Could this be a fuse or wire issue? Any suggestions?

 

Try pressing the window lock button and the other lights should light up.

 

the window lock button cuts power off to the switches for the other windows and the lights go out.
