Re: 80-86 Heater controls
Steve's right about the possible leaf blockage. Was the A/C working okay this past Summer ? That ought to tell you if the airflow is blocked by leaves.
Up here reverse flow flush outs are common place in repair shops or amongst do-it-yourself types (like us). This is an effective way to get heat back in your system and most rad shops will be happy to do it and change your coolant and even your T-stat for you for a nminal fee, if you don't have the time. All you need is a couple of T fittings with hoses connections, spliced into your heater hoses and a garden hose.
I've mentioned it before, if you're really wanting more heat, stick in Stant part #13352. That'll give you a 205 degree T-stat. I had the joy of changing the T-stat on the Ford and cut an 1/8" off the tough bolt and used the wire trick on the bolt and it went a lot better. Another trick we snowbelters do is block 50% of your rad off with cardboard.
Lastly, when you're done pointing the heating vents at your hands and the defrost has cleared the window, put the control on "floor". Heat rises and you want it to pump out as low as possible upon delivery.
