So the first problem has popped up on my Laser Blue V70R. Yesterday as I was driving, the passenger window stopped dead in the middle. The switch pack on the passenger door is no longer lit up. The master pack on the driver's door is relatively new and that wouldn't put the passenger window up or down either. Do you think I am looking at a dead regulator, a new switch pack for the passenger side, or something as simple as a fuse? Advice appreciated! Thank you!
