I just replaced the blend door actuator and that is working. The air started out getting hot and stayed hot. When I adjusted the temperature on the panel, it started blowing cold air again. I put temp back on 90 and the air was still blowing out cold. I am trying to guess it's one of 3 things. Cabin Air Temperature Sensor, Heater Control Valve or the thing that controls the heat and ac panel needs to be replaced.

When this occurs, there is loss of power like plugs are fouled out and sputters when I press on the gas.

swapping whole assembly from 98 what will I have to do

I'mhaving HID Conversion kit installed. Mechanic tells me dimmer switch has gone bad, although it seems to work to me. The switch changes from high beams plus gold side lights on to just gold side lights on. The low beams aren't quite connected yet. The low beams should stay on during both high and low option, right? This switch is expensive and this doesn't make sense to me. The switch should only turn high beams on & off, right? He said the switch going bad is a common problem because of the light problem. If this is true I don't want to buy a used one.
