Alright so last night I posted on installing my thermostat and what not. Today, I come with some more dilema on my 2002 KJ 3.7L V6. Well, the thermostat was changed, the water pump was changed, system was flushed and I still don't have any heat when I place it to heater. All I get is some luke warm air. On the control panel, all four speeds work, tested each and every position and they all work as upon switching positions I hear the flap opening and closing so I know its not the blower resistor. Reservior/Tank have sufficient coolant. No overheating at all. Too much freon in the system? I dont know what else to look for. Please help me figure this out its driving me nuts!
