SOURCE: My 2001 BMW 325I Heater fan comes on when heat or air is off.

From your discription I feel like it is only the resistor that is at fault.

SOURCE: My BMW 330i is still running hot after replacing

It could be several reasons...1. make sure you dont have to bleed the coolant system, on some cars you have too, because there is air in the system, and the car will overheat..2. Your waterpump maybe bad also..3. Double check your coolant temp sensor, and or coolant temp switch..maybe faulty..4. Check your radiator cap...seal could be bad, and not sealing correctly...Question..How long does it take before it overheats...and are you getting any white or grey smoke out of the tailpipe? If so, then your head gasket is blown...Goodluck

My Wife's care overheats and the heater only blows out cold air.


check that the thermostat is in correctly as it will cause no circulation but overheating. have a compression test done to eliminate head gasket /cracked head. There could be a blockage in the heater core but I am thinking that by passing the heater fan he has also by passed the actuator( coolant valve) for the heater core. Water pumps suffer from bad bearings and very seldom anything else. check that he hasn't blocked off the water to the heater core as well
the throwing back of the coolant is the boiling of the coolant in the block ( bad head gasket) due to lack of circulation. It may be a blocked radiator as flushing doesn't fix the blocked cores . If that is the case a new radiator is in order.

Car heater blows cold air


It could be the heater control valve make sure the vacuum line is connected to the valve and that it is working properly. If it is not replace the valve. Hope this helps.

Cause no heat temp gauge red lined in


sounds like the thermostat is stuck shut..unless the head gasket is blown somewhere.. it will pump the antifreeze level down to form an air pocket.. this will cause overheating constantly check each cylinder for even compression..the lowest reading will most likely be the blown cylinder..

2001 ford winstar top radiator hose stays cold, even close to the thermostat area i can hold on to the housing after the car has ran for 30 minutes, heater blows luke warm to warm at times, but not...


Check the heater hoses for warmth at the heater core. Some designs do not use a waterflow valve, but instead always have heater core flow and use the air flaps to regulate heat.

Now there is a difference in some thermostats and the housings. Barely noticeable are the locking tabs inside the housing and on the thermostat ring. If you have this setup and the thermostat is not locked in place, you could get some bypass around the thermostat.

If you have an electric cooling fan, the Relay may be stuck, keeping the electric cooling fan running when it should not. This would overcool the engine.

Please rate my info.

My 2003 325i blows cold air, heater never heats up, what's the potential causes/cures?


Potential causes: Low coolant- fix by adding coolant Thermostat stuck closed- would also cause engine to overheat Thermostat stuck open- would eventually blow at least luke warm air Heater core plugged- Get it backflushed or replace it These are the most common causes

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.

No heat/defrost 01 corolla


Sounds like you have air trapped in the heater core when you flushed the heater core. loosen the upper most heater core hose and run the engine untill coolant seeps out. Wait until the coolant has reached running temperature.

Heater blows cold air


maybe the heater matrix could be at fault, thats the bit that controls the temperature in the car.
