i just did a tune up on my bug . i replaced all the plugs wires cap rotor points everything complete tune up but no i have a green light on my speedo gauge it has like a curly que by it i dont know what it stands for maybe all systems goo or what ?
its for the rear window de-fogger. nothing to worry about! look under the dash to the right of the steering wheel and you will see a little toggle switch. flip it and the light will go off. chances are the de-fogger doesnt even work, well, after 40 years my rear window de-fogger doesnt work on my '70.
look on this pic at #18. thats the switch!!!!
