If you're talking about the control panel in the center of the dash, where the radio and ashtray is at, you only need to remove the cover plate. You can then work on the AC/Heat controls without removing the whole dash. It's a little tricky if you take out the whole AC control panel, just take your time with the 3 or 4 hook-ups and cables. The HAynes manual helped me when I was working on my 88 parts Bronco. I took everything out of the center section before working on the gauge panel and rest of the dash. It is a pain to take the whole thing out!!!
