Hello guys; I have a 2009 Escalade ESV, yesterday the driver side front seat stop working, it will not move back and forth or anything. The passenger seat still works fine. At the same time both key fobs stopped working and on the DIC unit the tire PSI reading for front and rear tires show dashes now, no longer shows the tire pressure numbers. I'm thinking a control circuit issue but I'm no mechanic so any help this forum can give would be appreciated!
