I have a 2004 Tahoe LT with memory seats. The driver seat is giving me issues. At first it seemed like something got stuck in the seat track as the seat would not move all the way back. I found out that the switch on the side of the switch was acting funny. If you move it forward the seat goes back and if you move it back the seat goes forward. When you hit the memory button it tries to move the seat back, but it does not work. I have read that it could be the module/switch that controls the memory. Is this a common problem and how can I test?
