Default 1986 C68 bulbs

I've searched and couldn't find an answer. What bulb does the early C68 climate control take? One light is out and it's annoying the hell out of me.

My parts book does not show the individual climate control unit parts. My suggestion, remove it and see if the parts store has a replacement.

Since nothing here (in Ver-mont) is "local" it would be much wiser to have the correct parts in hand when I rip open the dash. There's a dozen threads concerning the dash panel lights, surely someone has replaced their climate control lights (and remembers what bulb they used.)

The shop manual says it's a #37 on page 8B-24.

That matches the radio bulb and they're on the same dimming circuit, so it's probably correct.

The #37 is rated at 0.5 CP (CandlePower) vs. the #194 at 2 CP. The #194 is larger.

Thanks Cliff. My FSM doesn't mention climate control. But it make sense that would be the same as the radio.
