Hey all I have an '04 Escalade and have started having issues with the power seat. When I put the key in the ignition to start the vehicle the seat either does nothing or shakes for a few seconds. Also, when I shut the vehicle off and pull the keys, instead of going into the "exit" position it instead starts lowering the back of the seat bottom all the way down. Any suggestions for me to fix this or do I need to take it in?? Thanks!
