I need to replace the light bulb (194) in my '82 Conquista...how do I remove the Heater/AC control?

Remove the trim panel first. There should be two phillips head screws below the radio. You'll then see the hex head screws surrounding the heater and a/c control. Should be 4 7mm head screws. Once they are removed, you should be able to pull the control out far enough to change the bulb.

Didn't know if I had to pull radio first...thx will try that.

You don't, just the trim plate around the radio and heater controls, once the trim plate is removed then you have access to the heater control for removal
