Cooling System Temp gauge doesn't move and heater blows cold air and when I accelerate the gauge goes up and it starts to blow hot air. I'm not losing any water and coolant looks good as well as the oil so i've ruled out the head gasket. possibly the thermostat?

Heater blows cold air. After the truck gets warm if I turn the heat on and off and move the temp control lever from hot to cold and back up to hot it work. Today I noticed the temp gauge went to 215+ before the stat opened.
I believe your thermostat is beginning to fail, although the truck really isn't all that old. Still, it is 5 years old, and has been through many heat cycles, so I would change the thermostat. Change--drain completely and replace--the anti-freeze a ... 2006 Chevrolet Silverado

I have a 96 Town and Country 3.8. The heater started to blow cold air and the temp gauge was not at normal operating temp. (Usualy is about halfway between hot and cold). I have changed the thermostat and it worked fine for a few days then back to cold air from the heater and the temp gauge is reading below normal as well. I think the new thermostat is stuck open again. I did not find any trash in the system. The radiator has about 30K mi on it too. The Radiator cap is about a year or two old. W

But, as soon as you start moving again, engine temp indicator drops back to cold and the air cools off as well. Please help me.

1995 buick park ave. 3800 series II. After letting the car reach full temp I turn on the heat and it is nice and warm for about 30 seconds, then I hear the sound of the air change, and the display flashes for another 30 seconds or so, and cold air comes out. The temp display stops flashing and displays an accurate outside temp, but cold air continues to blow out. I can shut the car off and start it again and get warm air for 30 seconds again. Does not matter if I move it to floor, vent ect.

2005 tahoe will not blow air in the front when at idle or setting still. Setting still you can run 2000 rpm still will not blow. When you start moving about 20 mph it will blow but only 1 speed (about mid speed) no matter what you set the controls on. Slow down to stop and it stops blowing. The temp control works so if you set it on 60 degrees it blows cold on 75 it is warmer. If you turn teh heat on it blows hot but only when moving and you can not control the fan speed.

Air conditioning My ac blows pretty cool air for the most part. It just will not pull the cab temp down to an acceptable level even on Max AC with fan on high. Upon occasion, it will stop blowing cold all together for a few minutes. It will then blow cold again. I have a cheap gauge and put it on to check the leve of r123a, but it shows it to be at the max range or just a fuzz above that. Any help here?

No heat in 2000 cavalier blows cold air and temperature gauge is not moving off of cold
Could be a thermostat problem or your heater core! ... 2000 Chevrolet Cavalier
The Rear heat/ac controls quit working. It does not blow any air. Also, my heater only works if the temperature gauge is on max. Anything less than the max temp, it blows cold air; however when it is on the max temp, it is so hot it will sweat one out of the vehicle. We were trying to look for a manual to figure out what was wrong so that it can be fixed. Thank you

I have a 1996 Ford Explorer, the temp gauge goes up just a little bit above normal that is when I smell antifreeze and I get a little bit fogged up and film on window then it goes back down to normal. And it all clears up and is okay for the moment, antifreeze fluid is fine the overflow is fine nothing on the ground. I have hot air blowing with the temp control knob when it is on cold and hot. No cold air coming in... Hummm not sure the problem please help. Is it a thermostate or heater core
You should look under the dash on the passenger side to see if there is any evidence of antifreeze on the bottom of the heater plenium. What usually starts as a small leak in the interior of the plenium will eventually lead to the heater core leakin ... 1996 Ford Explorer

Hello, I have a problem with a heat, mechanic replaced thermostate, water pump, radiator, also blowed air out heater core. But problem still there. It gives me cold air, water gauge moves a little from cold toward hot, then drops down ( several times) then it goes to middle and I get hot air and again can drop to cold. Seems mechanic changed everything. Does anyone knows what might be causing this... Thank you
