Check antifreeze level first and fill if low.. then check vacuum controls in and under the dash and the hood.. may be a stuck baffle door or malfunctioning valve in a hose somewhere..good luck..

Could be a variety of problems iam afraid but check the coolant level when cold and make sure you put antifreeze 50% in fill it up the top and make sure the expansion bottle is full as well then try it as if level is a bit low then the heater is the first to suffer

SOURCE: 2000 GMC Sierra 5.3 Litre, won't blow hot air

I experienced the same head ache. First attempt was to replace the thrmostat and after taking it apart I realized that there was nothing wrong with it. I then removed the plastic cover/panel located under the dash board on the passenger's side. (only a few 4-5 smalls screws) Removal will enable you to see the on/off switch/gate moving/rotating as you turn the knob to hot or cold positions, on the control panel. If that switch/gate seems to work ok, then the trouble is within the heater core. Many mechanincs suggested that I replace the heater core. A very expensive proposition.
I checked the heater core supply/intake hose and found it hot to the touch, while the return hose was nearly cold. It was definitely a heater core blockage. I removed both ends (supply and return) hose connections/clamps. They are located near the fire wall in the engine compartment. A special tool is very helpful to remove those clamps easily and to replace them as well. It can be done the old fashion way but this tool was a life saver and reduced work time to just minutes. (Tool is $70.00 bucks at auto parts store,so I borrowed mine from a mechanic/friend)
I then hooked up a garden hose to the return end of the heater core and reversed the flow of coolant/water through the heater core. My truck is a Sierra 2000 and I refuse to see how a heater core could get clogged up with clear coolant alone. To my surprise a flat piece of rubber about the size of a quarter blew out of it and the flow of water became unobstructed. I reconected the ends of the hoses to the heater core, replaced the lost antifreeze & everything returned back to normal. No money spent for something most mechanics suggested I replace control valves/switches ($280.00) replace heater core ($500.00) etc etc. I am glad I was curageous enough to tackle this myself and save a few pennies. Good luck, and I hope this will work for you.

SOURCE: 04 Jag S type middle air vents cool, sides hot. Recirc hot.

here is what you do. look on the passenger side front near the bottom of the radiator. there you will see the dccv or dual coolant control vavle. it will have your two heater hoses running to it and another hose from the radiator under it . once you have identified it , feel and look around it for any signs of leaking. barring any leaks, disconnect the connector, turn the ac/engine on and usining a tester , test for voltage on each of the three wires.if both outer wires have no current ( the middle wire yellow- will have current) then your problem is the control panel. if the control panel is not a navigation it is possible to easily repair it. replacing it can run from 600.00 to 1500.00 depending on who you goe to. oh by the way its still some data that you aint looked at. holla back if you need more help or a repair of the a/c control panel.

SOURCE: Temperature gauge fluctuates and the heater blows cold air

Definitely check your fluid level in your radiator. Top it off all the way. I've seen that happen multiple times on cars that were low on anti-freeze. If that doesn't work try replacing your thermostat. It's cheap and the easiest place to start if topping off the fluid doesn't get you fixed up.

1998 Toyota Camry 4 cyl.only blows warm air from heater when car is unning for say ten min. When I start driving the temp gage goes down to cold and blows cool air, no heat. I changed thermostat and...


Your radiator cooling fan will only come on when the engine temp has reached the point where it needs to have air forced through the radiator and thus bring engine heat back down to safe operating range. If your heater is not working check to make sure the fresh air vents aren't stuck open (are the controls stiff or not going all the way across?) check also that the heater shutoff valve lever which is usually situated on the firewall at the rear of the engine and can be found easily by tracing the hoses back from the thermostat housing aren't bent and/or seized up.

Would the heater control valve malfunctioning make the engine overheat blowing hot air out the heater one moment,then not blowing the hot air, temp gage spikes 225 plus. The motor takes awhile to heat up...


Heater control valve malfunction will not cause engine to overheat unless coolant is leaking externally...Overheating going down the road can be the result of a few different things...Partly clogged radiator...Insufficient air flow due to possible fan problem...External coolant leak...Make sure fans are operting properly and have cooling system pressure tested for leaks...Gaining and losing heat on the inside of the vehicle usually means system is low on coolant but you must find out where coolant is going

I have a 1993 Acura Ledgend. For some reason my heater does not continue to blow hot air, it does for a few minutes and then begain to blow cold air. It does this often now. It works and then it blows cold...


first check to see that you coolant level is full, check it after the engine has cooled down,so there is no pressure in the system. otherwise you possibly have a head gasket in the early stage of failure
