    OK it's the heater core, are the hoses going to the heater core that you replaced getting hot?

Ok then the problem is a part called the blend door, it is moved with a small elecetric motor, if it fails the air can not be diverted to the correct location for either heat (directed to heater core) or AC (directed to evaporator core) cold air

Replace thermostat 03 explorer


Heater circuit of coolant system could be blocked by a trapped air bubble or a blockage in the heater core. Try having the heater core back flushed. Any good auto shop should be able to do this for you if you don't know how. To remove the trapped air bubble put a coolant flush valve in the heater core line that returns the flow to the water pump inlet. Connect a washing machine water hose to it then warm the car up, turn the heater temp control knob up to the max then open the flush valve on the heater return line to allow the air to be vented out--close the valve when the coolant flows out.(use caution he water blowing out of the hose will be hot. point it safely away into a bucket to catch the coolant) Check the thermostat for proper operation while you are at it so you know it is good. Put it in water on the stove and bring the water up to the thermostat set temp to see if it opens.

1995 BMW 525I over heating issue. I repaired head


Hi, Sounds like you have tried about everything. Ok the aux. coolant switch is for the electric pump for the heater core will not cause an over heating condition just a longer warm up of the heater core. Has the cooling system been bleed properly if there is a trapped air pocket it will not let coolant circulate. Was the new thermostat installed correctly? They have a vent that needs to be towards the top or they trap air on the back side and cant take an accurate reading to open and close. Other areas to look at would be proper operation of the fan clutch, if they fail they can cause the fan to not lock up properly and supply enough air movement through the radiator. The aux. electric fans and their temp switches do you hear them coming on are they coming on at the right temp.

99 jeep cherokee problem w/ heat I replaced the blower motor, water pump,radiator, thermostat and flushed the coolent system. Still getting little heat. I'm thinking heater core or head gasket... Is there...


It sounds like the heater coil needs flushing out or replacing or the heater valve. Look on the engine firewall and make sure the heater valve is opening. If not open it manually and check the heat level. If that produced heat check the condition of the heater vale cable (or vaccum hose).

Blower working but dont have no heat i changed the thermostat still not working im hoping its not heating core any suggestions


if the cooling system is not clogged and the water pump is ok then there may be air trapped in system, bleed air from system if need be. if air is trapped in system you will not get any heat. start car let it run take cap off of coolant tank then find bleeder for the coolant system, open bleed screw and air may be trapped in system.make sure coolant is at a proper level. do not forget coolant tank cap when done.
