No your thermostat is stuck open which will not hurt the engine. but needs to be replaced, the thermostat is what allows the engine get up to operating temp. before allowing water to flow through the radiator and when it is stuck open it doesnt allow the engine to reach operating temp. so the heater never gets hot. I hope that helps you out.

SOURCE: Problem with No Heat on 2005 Chevy Avalanche - Cooling System?

it is most likey a sticking thermostat it either gets stuck closed or open in your case closed so collant isnt getting to the heater core and all you get is cold air blowing into the truck.
its a simple fix you can either do it your self or take it to a mechanic. now remember there are differnt thermostes so think about the climat you live in and get one according to that

take the cap off of the radiator (whil engine is cold) start and run the vehicle. keep runnig 30mins after the vehicle is hot keeping notice of the rad fluid level.
keeping the cap off will prevent the pressure build up that woiuld keep the air in the system, keep adding water or antifreeze as the level goes down. this may take an hour or so.
also with the cap off, you will be able to see if your water pump is operating correctly. you will visibly be able to see movement in the rad when the pum is engaged.

SOURCE: 2006 Chevy Equinox a/c works great but no heat what so ever ?????

If the blower is blowing air just fine, but you cannot control the temperature, you need to listen to air coming from the vents while turning the temperature from hot to cold. If you do n ot hear any change in airflow, then you may a temperature door in the dash broken. this is becoming a common problem on the Equinox

Heater doesn't get hot on 96 chevy truck. Blows good, just cold. Replaced thermostat, flushed radiator. Any ideas?


Air Temperature Control Blend Door Failure No Heat or no AC (dependes on where door sticks)

In all modern cars there is a tiny DC electric motor driven gear drive that moves a plastic door that blends heated and cooled air from the AC and the heater core, this is called (interestedly enough) the air temperature control blend door actuator. The motor that moves this door fails because the door starts sticking from warping, most common complaint is no heat but it can be no AC as well. To replace these parts (blend door and blend door actuator) you must remove the entire dash from the car. Always have this problem confirmed by a dealer or qualified repair shop as it is a very expensive repair.

Other causes of no heat in the cabin are engine thermostats that are stuck open (engine runs cold) or air bubbles in the cooling system.

99 accent stopped blowing cold air


HELLO
THE 1ST THING THAT MUST BE DONE HERE IS TO HAVE THE AC SYSTEM HOOKED UP TO A SPECIAL AC PRESSURE GAUGE SET TO SEE IF THE SYSTEM IS LOW ON CHARGE DUE TO A REFRIDGERANT LEAK. THAT IS THE MOST COMMON CAUSE OF NO COOLING IN ANY CAR OR TRUCK NO MATTER THE MAKE OR MODEL

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.

Our 99 astro van has been setting for about 4 months. It was in the shop for a ignition coil and back on the road. Now the heat will not work, the fan is blowing but will not heat up. also the temp gauge...


I am thinking the thermostat is stuck closed. Take of the top radiator hose and take off housing and put the thermostat in a pot and heat up to boiling temperature and see if it opens. If it doesn't replace it. This happens when a car is not used for a long time.

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.

97 Ford Econoline air conditioning and vent settings blowing hot


I know from experience that if the coolant is to low ( not just the freon levels in the compresor but the antifreeze/coolant level as well) the AC system will not cool and will blow hot. Check the coolant Antifreeze and freon levels, even with the Coolant being a little low my 1998 Ford E150 Van will blow hot. After you have ruled out of these possibilities and the chance it is the thermostat most likely the problem is what Ford calls the "Flap" it controls the air flow through the vent system when you switch from Heat to AC. When the Flap is working it closes off one systems air flow so as to not interfere with the current climate selection.
