No Heat Help Fffrrreeezzziiinnnggg

I HAVE NO HEAT IN MY VETTE CAR CAN RUN FOR HOURS AND STILL NO HEAT WHERE DO I START???????????

First, did you have this car last winter? If so did the heater work last winter?
Does the haeter fan run?
If you bought the car recently, check and make sure that the heater core is bypassed or not. Then you might have to replace the thermostat with factory spec.

Is it the electronic or manual system?
Might just be the cable or vacumm line that controls the heater vent door

I would say pack up and move to FL
you could touch the rad hose or heater hose, notice I didn't say grab, so see if it is getting warm and kinda trace it back.

Yeah. That little vaccum diaphragm screws up on me sometimes and cuts out the heat for me.

if u have electronic air, then i bet its the door that open and closes next to your heater core.
i had the same problem. VIGMAN helped me out and now have a ton "O heat.
to fix my heat problem i had to replace the electric motor that opens and closes the flap/door that controls the heat flow thru your heater core unit.
