Check radiator fluid level. The heater core sets higher than the engine. If fluid gets low, air bubbles will go to the highest point. The heater core. Check temperature guage. Is engine warming up to normal range? If not change the thermostat. Also check radiator cooling fans with engine warm.
On my car if I set the heater control on anything other than "vent" both cooling fans come on and the engine will not warm up. (still haven't figured that one out) I just run the heater in "vent"

If heater warms up when engine is held at high idle(2000rpms) then cools down at idle, you most likely have air traped in the system.

Check the heater core for a clog or the heater control valve. The easiest was to check these is allow heater to run for a few minutes and check the two hoses coming from under the hood against the fire wall. They should both be hot. If they are not, you have one of the above problems. Start with the heater control valve and replace it. It is much cheaper than than a heater core. Next, you will need to pull the lines from the firewall and see is rust starts coming out of the lines, if so, you may be able to flush the system and clear the blockage. After that, if it does not work, it will require replacing the heater core, which is no easy or cheap feat.

Let me know if there is anything more I can help you with.

Sounds like your hot/cold door is stuck on cold. Is the heat not hot either? If so that could be it. Perhaps your heater core. Good luck.

Heat only for 30 sec then goes cold


I would guess its possible that the cable that closes the flap under the hood could possible be failing.

Heater will not work, just cold air Ed


check the coolant level, if your blow motor works and your not getting heat the coolant is probably empty, the heat work when the engine gets hot and coolant starts to get hot, from there the blower, blows the excess heat into your car, low or no coolant means no heat

My heater core is good and my ac and blwer works but have no heat in my car


If you know for sure the heater core is good? How do you know?
If it is indeed good, then the Vacuum valve that controls the water flow into the heater core is bad replace it.

Engine hot ... heater cold ?


Check the coolant level, it could be as easy a fix as adding coolant because it's low. Low level causes engine to overheat, and low level won't circulate to heater core, so no heat situation even though engine is running hot. Let me know if this fixes it, if not I'll help .
