A/C Panel light

All the lights in my interior work except for the a/c heater contol. I'm guessing it's a burned out bulb. Where is it located and how difficult is it to replace?

Its located in the unit. Pop off the plastic dash bezel. There are about 100 screws. Okay, not really, but there are a lot. Pop that off, and from there it should be self explanatory.

A plastic socket behind the controls. Should be able to reach it from under neath past the radio.

The bezel isn't all that hard to remove, but the gauge pod has a plug & receptacle plus the speedo cable, which is a pain to work with. I believe there are only 99 screws in it...

I've removed dozens of these dash bezels and it's no big deal (don't forget to remove the radio knobs). Once that's off, just remove the three retaining screws for the Temp Control and pull it forward enough to replace the bulb. I really don't think it's possible to reach up under the dash with the radio in place as it fills that entire cavity below the Temp Control.

Thanks guys, I'm gonna be replacing the radio with a retrosound unit, so maybe I can get to it with the radio out.

You can get to it with the radio out, but it's just easier to take the 3 screws that hold the head in place.

Word of note on the Retrosound units, if you are expecting great sound out of the head unit by itself, don't. We installed one in a 71 Chevelle convertible, and it barely has any more power than my stockish 81 Delco AM/FM/Cassette and doesn't sound as good. They really need an amp behind them to sound any better than the factory units.

My 77 with cheap speakers all around (4x6s in the front center mount and 6x9s in the rear) can get decently loud with the windows up at speed, and with all 4 windows down, can still be heard quite well even though I don't have a stereo package shelf, so the rears are muffled. In my friends 'vert you can't hear a thing with the top down or with the windows down and it has 4 speakers, 4x6s in the outboard stereo locations, and some 6x8s mounted on plywood behind the back seat.

I'm not that big on a sound system. I just want something with fm and an aux input.

btw is the sylvania 168 bulb the correct one?

The bulb for the controls looks like a hot air balloon.
