Kent & Sally,
Do you get any heat at all once the button is pushed & the temp bar is all the way to the right? (once the car is warmed up & in motion, you should feel at least a 'trace' of heat directed to the floor. When you hit the A/C button, does the compressor engage? If not, you may have a simple vacuum leak to the control head or a bad electrical connection.
On my '67 Crown Coupe, I found that ALL switches (esp the dash switches) were quite dirty, so I took out each one & cleaned them with tuner cleaner (Radio Shack, etc) & now everything works as it should!
Before attempting to remove the panel switch, spray a bit into the switch opening, then gently turn the switch "on-off" a few times...this may do the trick. If not, removing the A/C cluster is simple, really.
Let me know.
Carl
