Hi All
Can anyone tell me what the white turner? switch below the housing for the dip switch and indicator is for it appears to be just a piece of pipe? I do not have a handbook, and can not find anything in the manual.
I am intrigued to what its for.

I believe you are referring to the intermittent wiper speed dial.

mine has that but it does nothing....

The knob varies the leakage rate into the vacuum switch on the wiper delay unit fixed to the wiper motor . It should alter the delay time.

Can often be fixed with a new bit of sponge at the wiper moter end of the tube.
