My 2004 gmc sierra hd2500 has been setting for a few weeks and before I parked it I took it to the car wash. Today I got in and tried to put the driverside power window down and nothing so I tried the passenger window from the drivers switch and it work but still no drivers side window. Then I drove down the street and tried to put the turn signal on and nothing both directions. So when I got home I checked the rest of the electrical and found the fog lights didn't work either. I sthis a ground problem, fuse, relay?????
