Question about 1999 Pontiac Firebird
I do not believe the heater core is bad because it is not leaking. could it be clogged? It is blowing out air but only cold air..
You can remove both inlet and outlet heater hoses from engine put a garden hose to either end to make sure it is flowing properly, they do have small ports so it is easy to clog. A few more things to check, always use a thermostat, make sure all air is removed from system there should be bleed valves on the highest point of the cooling system. And lastly check water pump for good flow.
