I have a problem with my power drivers seat on my 2010 Impala LS. The seat moves forward and backward fine. I can move the seat height up just in the back. The problem is the switch that moves the seat height up in the front does not work. I had no problem using that switch until one day when I used it and nothing happened. It makes a noise likes its trying to work and nothing happens. I moved the seat back and fourth in various positions and nothing happens. Because of what happened I can only move the seat back and fourth unless I want to sit at an awkward angle and fall off.
