I have a 2005 grand prix gt temp guage reads normal and heat is on and warm when start driving heat gets colder or if i change to defrost its cold air doeasnt stay hot car doesnt over heat though changed...


The heating coil is probably getting plugged up. You may have heat at idle or slow speeds, but once you get going, there is not enough coolant going through it to stay warm. Get the system flushed or replace the heating coil.

We have a 2005 Grang prix and the heater will not but out much heat. We checked the coolent and it is full


Open the hood and with the heater running(be careful PLEASE), feel the lines going to the heater core(2 hoses running to the firewall, to the blower motor). Is one of them hot? If both are cool, your relay valve to allow coolant to the heater core is stuck. It will have to be replaced. Is the blower fan running( that's the fan in front of the firewall)? If the valve opens but no fan running, you will not get hardly any heat. If all that is working, You have a problem with the vent control valve(that will open the hose duct to allow heat to go through the vents). It works off of vacuum. A hose may have broken (they are made of rubber), or it may be just stuck. Check these first, before looking at the heater core. I hope this helps you

The heater doesn't warm up in my 2005 Grand Prix. The blower works, but no heat! Is it just a thermostat or am I looking at something more expensive to fix?


if the tempature gauge reads normal warm the vehicle up and feel the heater hoses wich are located on the right side of the vehicle if one is alot warmer than the other you probaly have a plugged heater core remove the hoses and take the hoses off and run a hose through one of the hoses until it comes out clear. it could also be just low coolant and topping off the coolant could solve this problem temporaily but if it is low it is leaking.

My 2005 Grand Prix has no heat and my gas mileage is awful. would changing thermostat fix problem. also at night not sure if this has anything to do with problem only my blue temperature arrows light...


A FAULTY THERMOSTAT STUCK OPEN WILL EFFECT GAS MILEAGE AND CAUSE POOR OR NO HEAT CONDITIONS.THERMOSTAT NOT A HARD JOB TO FIX.ALL YOU NEED TO DO IS DRAIN OUT SOME OF THE COOLANT IN A DRAIN PAN.DRAIN COOLANT LEVEL BELOW THERMOSTAT.IF YOU HAVE 3.8L ENGINE THERMOSTAT HOUSING ON TOP INTAKE MANIFOLD.IF YOU HAVE 5.3L ENGINE FOLLOW TOP RADIATOR HOSE IT WILL LEAD YOU TO THERMOSTAT HOUSING.REMOVE HOUSING THERMOSTAT INSIDE THE HOUSING.IF YOU HAVE WATER INLET ANDTHERMOSTAT IN ONE COMPLETE UNIT OR HOUSING YOU HAVE TO REPLACE THE ENTIRE WATER INLET HOUSING WITH NEW THERMOSTAT.THIS TYPE UNIT WILL HAVE LONG PIPE WITH BYPASS PIPE WITH WATER INLET WITH THERMOSTAT. ONCE YOU REPLACE THERMOSTAT.IF YOUR RED ARROWS OFF AND HEAT STILL DONT WORK THE DEALERSHIP WILL HAVE TO CHECK IT OUT.WITH NEW THERMOSTAT AND PRESSURE CAP.MAKE SURE GET COOLANT LEVEL CORRECT.SEE HOW HEAT WORKS.IF NOT YOU HAVE A ELECTRICAL PROBLEM AT AC AND HEATER CONTROL SWITCH.

No heat in car ,new coolant ,new thermostat


Had the same problem and turned out to be that the Heater Core was clogged. Took it to a Radiator shop and they blew the system out to unclog it. Cost was $25.00. 2005 Grand Prix.

Heater doesn't blow hot air but the engine temperature warms up like it should


Check that the water level is correct in the radiator and make sure the water system is properly bled as if there is an air lock then this can cause the prob you describe and check the thermastat is working correctly by dropping it in boiling water and see if it opens fully.
