I have a 1997 chevy lumina the air nor heat comes out the vents and could i do to fix this problem myself? i change the coolant the car doesnt run hot or anything what could be the problem?
blocked heater matrix try flushing cooling system
Check the fuse to the fan motor(blower)
as long as water flows solid throughout the time of the heater center and it,s no longer leaking then it,s no longer the middle ! sounds like the two 2 issues ! the heater door isn't beginning all the way or the thermostat isn't beginning all the way !
You seem to have a heat exchanger problem or check your radiator pressure.
