I have a 86 vette that was in really rough condition when I bought it. I've gotten most everything working on it other than the heater. I can not get hot air out of the vents. Both heater hoses are hot so water is going throught the core and the shutoff valve is working, but I can not figure out what to check next. My "service manual" is a joke when it comes to the heating system. Is this probably going to be a elec problem with the digital control head or an actuator problem in the dash?
Thanks in advance for any help.
