2003 Hummer H2 V8 All Wheel Drive Automatic 71 000 miles
I have 2003 H2 and its water damaged. None of the gauges are working exept for their ligths. The front window power is not working either. I have grounded the heater from the body in order for it to work. The controls for the heater show that they are working but we can't control the level of how much heat we need. I already installed a new module but it still the same. It can be turned on/off by grounding the heater. When I ground the wire, the heater just turns on and stays on one level. I can change heat from windshield to floor or front but can't control how high I need the heat to be. I already installed the body module.
