unknown mystery switch

[vecoth]

I recently purchased a '71 280SL and it has a pull type knob switch on the center console behind the ash tray.  Does anyone know what this could be for?

This is the switch for the Hard Top rear window heater.

There should be a wire and plug coming up behind the driver's seat back. The plug attaches to the short wire coming out of the Hard Top.

Thanks for the response.  My hardtop doesn't have any wires or any lines in the glass.  Does this mean that I probably don't have the original top?

Possibly. You can confirm this by examining the hardtop for a serial number. You'll need to remove the top to see it. If memory serves, it's on the passenger side under the rear window embossed on the edge that sits on top of the car when it's in place. This number should match the hood (aka bonnet), tonneau cover and transmission shield on the undercarriage. The number is also the last series of numbers on the plate on the driver-side of the engine bay.

The were another optional switch that goes on the center console right next to the rear window defrost knob. Frankly, I forget what its function was.... Rear fog lamp perhaps? Anyone else remember?

You might not have the original glass, due to breakeage in the past, or a replacement hardtop.  Knowing what we know now about how difficult and expensive it is to replace the rear glass, it might have been cheaper for a p.o to buy and repaint a used hardtop than to pay to replace the glass!

By all means check for matching body numbers.  You'll know soon enough what the story was!

I have seen a front to rear fader mounted there(twist knob)for a 4 speaker stereo instalation. Not sure if this was a factory option.
