Trivial question on the 83 300D climate control unit

[ah-kay]

How many light blubs are in there?

The temperature wheel does not light up, all the buttons do. I normally would not care but I am upgrading the radio so it is as good a chance as any to check it out and replace the bulb if necessary.

In the W126 unit, there are 2 blubs and it lights up all buttons and the temp wheel. So there must be something missing in the 300D.

Any helps appreciated.

Four (4) bulbs. One for the temp wheel, one for the blower speed buttons (max, min, auto) and two for the main center buttons.

1.2W frosted glass type.

Might as well get 6 bulbs, in case you want to replace the bulb for the spider wiring on the LEDs (deep in the center console).
