Why does Temperature gauge goes up and heat blows cold air?
Your low on coolent! system set up to protect engine first so routs coolent away from heater.
1998 transport over heating. when the temp gauge is normal heater is blowing hot when temp gauge gets hot heater blows cool replaced thermostate Why would it be over heating?
This would indicate that the system is low on coolant when the gauge is hot. Not enough coolant to service the heater core.
What could be wrong if temp gauge reads cold and heater blows cold air on ford windstar?
I'm not a mechanic / technician but it sounds like your engine cooling thermostat is sticking open ( assuming that the electric engine cooling fans are not running continuously )
What if your 2004 silverado temp gauge runs above normal in town and the heater blows cold but runs at normal temp on the freeway and the heater works fine What is the cause?
thermostat
Why does heater blow cold at idle only blows hot air when accelerating temperature gauge shows normal Chevrolet Impala 2008?
If the coolant level is okay, I would suspect a restricted heater core. Try flushing the heater core.
The heater in your 95 Chevy Corsica suddenly stopped it only blows out cold air why?
In order for the heater to work, the radiator needs to be full of coolant; if it is , then run engine for 20 minutes and check temp gauge; is it at operating temperature? If not replace the engine thermostat; if it is at operating temperature then take your hand and place it on both heater hoses; are the both hot? if only one is hot then your heater core is plugged and it will need to be flushed or replaced if you cannot flush it.( The heater hoses are on the passenger side and go thru the firewall) I hope this helps you.

2000 2.7L Dodge Intrepid After the car warms up the heater works only when you are driving the car when you are parked engine still running the heater blows cool air. Where is the thermostat located.?
Either the water pump is unable to pump the warmed water into the heater core, or as you suspect, the thermostat may be sticking open. Do you have a temperature gauge or is it just a light that tells you when you're overheated? If it's a gauge, you should be able to tell when the engine is warm. If the temperature is much over 100 degrees F, you should be able to get heat out of the heater core. I'd be real suspicious of the water pump or possibly low coolant level.
How do you fix the heat in a 94 Chevy S-10?
add water to the radiator. believe that. if there is no water flowing through the engine, your heater will only blow cold air. if there is no water flowing through the engine and your heater is only blowing cold air, and not HEATING, your heater core is probably going out or will be soon. most people believe that if you have no water in the engine then your temperature gauge will run hot and you will know that you are overheating the engine. WRONG! your temp gauge only measures WATER temp. But if there is no water to measure, there is no temperature rise showing on the dashboard gauge. if you have NO WATER in the engine you can seriously overheat your engine and not know it because the gauge is not getting any hotter than usual (sometimes your gauge will even read cooler than usual).
Why does temperate gauge reduce when heater is turned on in 1997 Cadillac deville?
This is actually common for most cars. The reason is that the heater pulls heat away from the engine into the car itself.
Heater working fine temp gauge showing engine is cold?
Could be a failed engine coolant temperature sensor. Easy enough to replace and not too expensive.
Can the thermostat be bad if the heater doesn't work?
If you are not getting heated air blowing from the heater core and your engine coolant temperature gauge is showing LOW or below normal , ( then YES , IT'S POSSIBLE that your engine cooling thermostat is sticking open )
1997 F-150 Heater is blowing warm air not hot Would this be the thermostat or heater core Anti-freeze is full. Engine temp stays in the lower middle of the gauge.?
The thermostat is the most likely culprit. The major clue is that the engine temp stays in the lower middle of the gauge - the heater core would not cause this. The thermostat is most likely stuck in the open position - needs replacement.
