I have been having these problems with my 06 Zephyr. My front heated and cooled seat has already stopped working for the second time. The first time the dealer took 2 weeks to get the part and fix it. They had to remove the seat and the seat cover and replace the part. This happen last year in January. Now when I needed it isnt working again. I need to take it back but I was wondering if anyone knows if these has been an issue for the Zephyr's. Anyone know if there is a bulletin announcing this? Also I have had problems with my auto dimming drivers mirror. Sometimes it works and sometimes it doesnt. thanks
