Could be the diverter valve. It's the one located near the firewallmy heater is only blowing cold air in my 1996 - 2_bing.gif in the engine bay. The valve is in-line on one of the two coolant hoses that run through the firewall. Have a helper rotate the temperature knob back and forth, with the ignition turned on, and you watch to see if the valve is being adjusted. I'm guessing it isn't. Best of luck!

No heat, blows cold air


Possibly a plugged up heater core or a blend door not actuating properly, try to back flush the heater core. If that doesn't work may need someone to check it out more thoroughly.

96 Buick Park Avenue, heater wont blow hot air. How can I tell if it might be the thermostat or the heater core?


Start the car and let it warm up. After it is warmed up open the hood. Look for your top radiator hose, and see if you can squeeze the hose, if the hose is hard to squeeze, the thermastat is stuck shut. If your heater core was out, it would be leaking badly.

Not getting any heat, flushed out anti freeze and changed thermostat, still no heat


Look on firewall in the middle behind the engine but on top and you will see the heater hoses. You should see a vacuum type valve. These types seem to go out after a few seasons. Try to move it manually. If you can't then it needs to be replaced.

The heater blows mostly cool to cold air when the heat is set at 90 degrees. Coolant has been flushed and thermostat replaced


You probably created an air bubble, lock in heater core or the hoses that brings hot water to it when the coolant was replaced, you need to flush the system by loosening the heater hose at the highest point while the engine is running and is up to temperature.

92 buick park avenue won't blow hot air - temp control seems to be working


Make sure there are no leaks and that the system is full to capacity. After the vehicle has warmed up check radiator hoses for temperature differecial also check heater core hoses. A significant difference in temperature may indicate a plugged heater core or thermostat failure
