I've had a strange occurrence twice now with the drivers side power seat in my 2006 Silverado. Once when the truck was only a week old I opened the drivers door to see that the seat was moved all the way up, I have it all the way back and am the only one who has ever driven it.
Yesterday almost 7 months later I unlocked the door with the remote, and jumped in the truck, just before I could get the key in the switch the drivers seat started to move forward while I was sitting in it. I used the switch and moved it back to where it always is at.
I don't have the optional seat or mirror memory that I'm aware of. There are usually two little buttons on the door panel for that feature correct? The truck is a Z71 with LT1 trim.
Strange.
