fixed mine. for some reason the mirrors, both sides stopped working, including toilt and memory nothing worked.
I removed the drivers mirror glass and front cover and checked all connections. I removed the drivers side door panel and the triangular cover. I unpluged the mirror. I disocnnedted the baterry for 10 second. I reconneded the battery. I then tried the passenger mirror and it worked. I plugged the drivers mirror back in and it worked. fixed.
Ialso had worked on the rear door panel and the rear window switch stopped working. the drivers switch would work though. when I did the above procedure on the mirrors and unplugging the battery , the rear window swtich started working again.
