    There is most likely a valve, either mechanical or electromechanical, that sends coolant to the heater core. The valve is apparently stuck closed. Look for the valve between the water pump outlet and the heater hoses going into the cabin.

Could be heating control valve ( not cheap ) or could be air in the system.

SOURCE: leaking coolant from engine..

Unfortunately, This Problem is Going to Be Either a Blown Head Gasket or a Cracked Block. Just in Case, Check all the Hoses and Check and see if your Model Has a Transmission Cooler Installed, Hopefully on of these is the Culprit. Please Rate My Response! Thanks!

SOURCE: heater blower not working

I don't know if this is a long-term solution but I found it on another "how-to" website: on my 2001 E46 I removed the fuse (#50) for one minute. Something about the transistors inside the FSU (final stage unit, or blower resistor) resetting themselves with the constant power removed. I replaced it and drove home, which is a 1-hr drive, and the fan was on steady the whole time. Which it hasn't done in the 3 yrs I've owned it. I tested it at other speeds and it worked well. Don't know how long it will last though. If not, you need to replace the Blower Resistor - there about $75.

Why is my heat or air is not blowing and car is running hot


How hot is the engine running in degrees f? Does the radiator fan run?
With hvac turned on, check voltage and ground at the blower motor. If good voltage and ground, suspect the blower motor is faulty.

Heater not blowing hot air


IT could be one of several things: possible the blower fan motor is bad; or the valve that lets the hot water in from the engine to the heater core is not opening; or the door that lets the air flow past the heater core and onward to your vents is not opening. All these are controlled by your heater switch, via relays and vacuum lines. If the blower motor works well when you put power to it directly, but not when it is hooked to the car, a connection in the switch or a relay may be bad. if you get little or no effort from the blower motor when you hook it directly to a good battery, it's the blower motor itself gone bad. If you get airflow but not heat, it's the device which diverts the hot water into the heater core. and if its the door to let air flow over the heater core, it could be a relay, a vacuum hose or the switch.

In my 1994 1500 Chevy pickup the heater blower will not work. Need to troubleshoot.


There is not enough information to answer you question effectively. Is your heater blowing cold air or is your blower motor not working? A tell-tale sign of vehicle blowing cold air is bad thermostat. Also, check your fuses under the dash first and fuse relays under the hood before proceeding with the thermostat change. A worst case scenario could be your heating/cooling controls have malfunctioned.

My is heat is not work?My car is blowing cold air instead of hot air, I have a brand new heater core,the thermostat is not sticking,I got anti-freeze in it,It's getting cold in I need heat.Please help me


first feel the heater core hoses see if both are hot if so then your problem is in the blend air door must be stuck on cold. is your blower motor blowing cold air if not your blower motor might be the problem. the blend air door is down by the blower motor.

Heating Problem w/2000 Plymouth Breeze.


Sounds exactly like what my mom's car was doing as for the blower only working on high. It was the resistor... I assumed it was the climate controls and replaced them but it didn't change anything then i thought that i must be the blower motor and replaced that too but it turned out to be the resistor which is under the dash on the passenger side of the car.
