2004 Impala Heater Not Working, but blower does

Check the coolant level. If the coolant is low, it will cause air to get trapped in the cooling system, so it can't pump the hot coolant through the heater core. Remove the radiator cap, top off the coolant, put the radiator cap back on, fill the reservoir, then bleed the air out of the system from the bleed screw located on top of the thermostat housing on the right side of the engine where the heater hose goes out to the radiator. If this problem happens again, look for coolant leaks.

blower dont work

coolant was very low. filled the reservoir, bled the air at the hose connection that enters the engine block. did not correct problem. air blowing at windshild is cold.
