Change you rad cap first this will cause the overheating and then go from there as this actually sounds like two seperate problem the other sounds like a plugged heater core

The heat blows cold and hot. Is it the resistor module or the themostat


The resistor controls fan speed, not temp.
If the heat comes and goes, it could be the thermostat, or the radiator could be low on coolant, or have air pockets, or one of the blend doors may not be working correctly.
The blend doors direct air thru the heater core and the vents.

Heater blows cold air,replace belts,themostat,accuator(door llender)


try flushing your coolant system. if you have air compressor.remove hoses to heater core and try ro blow it out. also with the car running see if the hoses are the same temp. if not try blowing out the heater core. also start the car and see if the water pump is pushing water out of the hose goimg to the heater core. also a bad radiator cap could keep it from heating up.let the car run and see if the top hose gets hard to where you can not squeeze it. if you can than replace the radiator cap. hope this helps leave comment.

Heater on 1995 Chrysler Concorde stopped heating. Replaced water pump and thermostat. Blows semi warm air out of one dash vent and pure cold out of other dash vent. Does anyone know codes to reset?


there are no reset codes, did you bleed the air out of the cooling system? if not do this procedure, if that doeasn't fix it u have a failed air temperasture control blend door motor actuator.
The generic method of bleeding air from the cooling system is to use a floor jack and raise the front of the car as high as poss, then fill the coolant recovery tank full and run the engine until it just starts to overheat, high end of normal zone on gauge, then shut the engine down and run cold water over the radiator core, this will self bleed the system and the coolant will be pulled from the recovery tank, repeat as necessary, never let the recovery tank run dry or more air will be pulled into the cooling systeml ,

What could it be


Hi, I think you have an airlock in the pump,You need to drain the water totaly when stone cold.Drain radiator and disconect hoses from waterpump and top hose from themostat. Reconect pump hose and add water slowly into radiator through top hose untill rad is full then squeeze bottom hose vigourously,You ll feel the water tension in the hose, Connect all hoses and top up water level. This must be done cold as hot and cold water will cause an airlock. Hope this helps you out.All the best.Phil

Over heating


Yes. It could be several things: a)water pump defective b)radiator core blocked or grille restricted c)electric coolant fan inoperative or blades broken d)thermostat faulty e)radiator cap not maintaining proper pressure. Good luck!
