Hi everyone! I just purchased a used 2007 GL450 just two days ago and I hope my problem now isn't a sign of things to come. The seat controls on the driver side have started to have limited mobility. When I got the car the seat would raise and lower, and it would move back but not forward (only work once in a while, but not no more). Since this is my wife's car she can't reach the pedals.So my question is if anyone knows how to replace the switch? Do I need to take the entire seat out or can I just pull the side panel off from the side. Any advice would help. Thanks.
