My 03 H2 is having some seat heat issues. When I press either button on the door, the indicator lights pop on for half a second & go off(no heat). When I put on the passenger side heat, it works fine until I turn the driver's side on, then after about 15 seconds they both go out. Sounds like a short, right? So I take off the plastic side cover & look under the seat...Sweet Jesus there are 4million wires under there! Anyone have a schematic or know where to start to look? I live quite a ways from the nearest dealer & would just assume fix it myself if at all possible. Any help would be greatly appreciated...
