SOURCE: 2002 grand prix, will not blow hot air, engine

With the engine warmed up feel the heater lines going into the firewall. You will probably find that one is very hot and the other only look warm or even cold. If this is the case the heater core needs to be flushed. With the engine cold remove the hoses at a convenient location and back flush the heater core. Reconnect the lines and warm the engine back up with the heat on.

SOURCE: 2006 pontiac grand prix, heat only gets warm not

Have you checked the coolant level? If that checks out ok... With the engine fully warmed up touch the heater core hoses where they go into the fire wall (about the center of the firewall). They both should be pretty hot to the touch. You'll likely find one hot and one warm. If this is the case flushing the heater core will likely get your heat blowing out hot again.

SOURCE: 99 pontiac grand prix smells hot after driving 30 minutes

If the temperature gauge looks good (under 3/4) its all good. If not, then there is a problem. If it smells hot inside, like moist and humid you will need to replace the ac filter, that can be located under the hood, close to the water resevoir, you will have to pull the ruber type gasket that is on the edge of the hood/wiper cover.

No heat 94 pontiac grand prix


If the engine is reaching normal temp, and both heater hoses are hot, the problem could be a blend door under the dash.

No heat 2007 grand prix


If the air coming out of the vents is not hot, could be a blend door problem or low coolant.

I have a 2006 pontiac grand prix 3.8l my heat only blow cold aair I checked the thermostat and the heart inlet hose is hot but the outlet hose is luke war what could this be maybe clogged heater core.


Ok fellow 2006 Grand Prix owners!! By trial and error, I went through the process of elimination because my car would over heat and had no heat inside. After changing the thermostat, I had to replace the water pump. However, after you do this, you need to open the inlet hose bleeder and let the air out a few times. This solved my issue of overheating and I now have great heat!!!
