Probably got some air in the system. Take radiator cap off, start car and let run until thermostat opens. Top off with coolant and continue to keep full as level drops. make sure coolant is flowing. Once level stops dropping, put cap back on. This should fix it. If not, please get back to us.

2000 caddy Seville ...after starting and engine warm turn on the heater and it blows cold air. Fan works / waiting for hot air and then all the sudden it kicks in. Engine at normal temp


Low coolant, if there is an air pocket in the engine it will make it to the heater core. Once there , the air coming out is cold/cool. Once the coolant fills the heater core, it gets hot. If the coolant is fine hot or cold, then have the HVAC system scanned.

providing your coolant is full cause low coolant will cause no heat
and your temp gauge is normal in the middle then most likely u have a bad blend door actuator usually on the passenger side

My cars temp suddenly ran in the red (hot) so i turned the heater on to cool it down and the heater would only blow cold air what could this be?


"ran hot and the heater only blows cold air"

First thing that came to my head reading this is check the coolant level.

Sounds like the water pump is cavitating . Replace water pump. Check coolant level also. Open the bleeder valve usually located on thermostat housing to remove air from system. close valve when coolant is present while filling. close radiator cap and top off recovery bottle to correct level. These engines are prone to overheating, do not let temp gauge get in the red.

Heat goes in and out and the temp gauge goes up and down


Your temp sensor has nothing to do with your heater. The temp sensor needs coolant in order to work properly. So first check the coolant level because if it is low your heater will act the way you describe. Once the coolant gets low enough the heater will blow cold. Another possibility is the radiator cap. After the engine has warmed up it expands when it cools down it contracts. As it is contracting if the cap is weak air can be drawn into the system and cause air pockets to form and will cause the same problem

My 2000 grand prix blows out cold air when its on heat


Could be air in the cooling system , try an bleed the system . On top of the thermostat housing is a bleeder valve , with the engine up to temp. open valve till coolant comes out . Is the coolant full ? What color is the coolant ? Have see where coolant turns like a muddy color an clogges the heater core an engine coolant passages . Check the heater hoses going into the fire wall ,are they hot ? Does your grand prix have manual or automatic climate control ? Duel zone ! Do you hear a clicking sound behind the instrument panel ? Bad temp blend auctuator .

If it is blowing cold air, that means the coolant level is low, the heater core has no coolant in it. Sounds like a head gasket is leaking.

You have air in the cooling system. With the engine cold, remove the radiator cap (or overflow bottle cap if no radiator cap) and let the engine get to operating temp. Add coolant if it is low. There is no way to guess which of the 3000 codes your car has set without scanning it for codes.
