Mystery knob on 68 Charger dash

[roadrunner]

Anyone know what this knob under the fuel gauge on a 68 charger is supposed to control?
Also, is this a factory installation with the separate bezel section it sits in??

That's not right, the factory rear defrost button goes there.

it looks like the speaker faber but ive always seen it at the bottom of the dash on B body's

looks like on a 68 charger the fader is suppost to be on the radio bezel

Interesting, thanks for sharing that thread. My radio does not work so I can't quickly confirm if it is a speaker fader (although the car does indeed have a rear speaker). Maybe this location of the fader is an early production year anomaly? The car is a Jan 8 build date. I'll have to dig in a bit it to confirm its function, and see if it looks like a factory installation.

could be i know 68's had some early production changes like the style of the ash tray and so on

It definately look like a speaker fader but looks like someone "customed" it up a bit. I think they should be on the radio bezel in 68. I have one that looks factory that is on the 68 rallye radio bezel

The separate bezel section is on all 68 rallye gauge cluster bezels I believe ... even with no rear defrost in which case there is just a blank there to match.

I would think that someone may have moved it up to make it more easily reached.

Here's a 68 rallye radio bezel w/fader.
