Heater blows cool air after the first initial heat blast

My heat goes cool after you first turn it on. you get a blast of hot air then it blows cool. Some one said maybe a blend door was stuck.

Is the coolant completely full? After verifying this, then the next thing is to check the vent switching mechanism. This means you have to get into the dash. Removing the area that covers the vents. move the vent control device and make sure it closes all the way, and opens all the way. check the seals, you can replace some of the seals with the tape you get from a hardware store to seal up doors and window. its a 1/8 of inch thick. usually white. use some lubricant to clean the hinges. Also if your car uses vacume to control or move anything, you need to check the vacume lines. they can have a pin whole and screw everything up.

My 2000 jimmy has heat problems. the heat goes from cold to hot to warm to cold etc. what could the problem be?


If the temp gauge is now more stable, the problem is in your heater system, not the engine cooling system.

Check the heater core, if it's OK, check the thermostat again, but it could be the heat switch too.

My 2002 saturn sl1 is weakly blowing luke warm air out when i have my heat at its hottest setting and my fan at full blast.


the best way to find out if the problem is in the cabin or under the hood is to touch the heater hoses when the motor is at operating temperature. turn on the heat full blast and feel the hoses; if they are both almost too hot to touch then the problem is with your blend door or its control mechanism. if one is noticeably cooler than the other then you,ve got a clogged heater core. if they are both cool enough to touch then your motor is running too cool

Heater blows out cool air only


Could be a stuck thermostat... or low coolant level. feel hoses going to heater core, if only one is hot while car is warmed up. i would say the heater core is plugged because this is where you get the heat for inside of car ! hot coolant goes through heater core and a fan blows it out to heat inside of car. if both are hot then the heater core is ok.

My 1999 Chevy Malibu runs hot? It started when it overheated. We changed the thermostat, then water pump, then temp sensor gauge and the temp gauge goes high but only when the heater stops blowing hot...


Air pockets will make the guage do that, and also cause your heat to come and go. Also, a poor radiator, as in rotting, or plugged up, will cause high temperature issues.

When the car is idling, the heater blows out cool air but when the car is moving, the heater works fine


When the coolant in the heater core is hot from the engine and your fan is on hot air will blow through the hot fan coil, i figured it out, when i stepped on the gas i could here the coolant squeezing by the control or limiter valve, because the higher rpms make the belt spin faster which makes the water pump pump harder causing more pressure, so when u idle that hot coolant will cool down from the fan blowing on it, u need to find the control valve and open it up to full blast, then hot coolant will always be flowing through your heater coil. ;)

Heater blower is on and no heat


you may have a problem with the cooling system-check your coolant level,if it is low top it off with a 50/50 mixture and let it warm up-then check the heat-you may have a leak-if no leak is found you might have a stuck thermostat

No rear heat


The rear vent system has a separate heater core/blower system. heater core could be plugged up or the coolant lines going to rear heater core are plugged. could also be low coolant/faulty water pump not producing enough pressure, or air in the cooling system which will need to be bled if so.

A/C is on and rear heater blows full blast from vent on the sliding doors


I had the same problem and the gear box that opens and closes the valve for the water flow through the heater core was stripped. I had it replaced because it is a bear to get to. Hope this helps.
