So I have recently purchase an 03 chevy 1500 2wd 4.3. To start my heat only works at the bottom passenger side vent and cold air blows out of the dash vents. I have check all coolant levels and cant figure out what the problem may be. If someone could help me out that would be great! Along with this the lights for the heat controls do not work any ideas?
