My 84' doesn't appear to have heat. I hadn't driven the car in cold in a while, it is mostly my fun in the sun car. I have replaced the heater core (although it was 20+ years ago) but there is no coolant on the passenger floor and the guy that replaced the heater core had a shop that new how to make them more stout so I don't think that is the problem. The car is digital and the controls all work correctly, but when I put on defronter it does go to 90 and start blowing but no heat.

Suggestions, I am not a mechanical person so I will need a shop to help me but my LA shop Z Expert is a little too far unless I cannot find someone local to guide to fixing it.
