I finally took my car to dealership to fix
the headlight and to my suprise they replaced the whole assy.. It is supposed to a sealed unit, so any moisture would mean that it had a leak. The heated seat also stopped working, well just the bottom part, the back still worked. They had to replace the whole bottom leather surface. Now I have one very new looking driver seat and a used Passenger seat.
