Heater in Firebird doesn't work
I've got a 1980 Firebird it has a Chevy 350 swapped into it. The heater in it doesn't do anything at all. It doesn't make any noise when I turn it on. I really just need it for the defroster because it's that time of year. When I press the button for the rear defrost it makes a click sound and the light comes on.
I'm not sure where to begin. Any advice? Maybe a wiring diagram for the heating system? Thanks
