more intermittent wiper timing

[overbarg]

Hi,

There was a thread a long time ago, where someone was complaining that the intermittent wiper interval at its fastest was too slow to be useful. I have the same complaint (01 C2 non rain sensing), and would like to move the interval range up a bit.

The thread below about the intermittent switch tells me that it's a simple rheostat, so I can move the speed range in one of two ways:

If when you turn the knob to make the wipers go faster (shorter interval) the resistance of the switch goes _up_, then I just have to put a resistor in series with the rheostat to move the whole range up.

If when you turn the knob to make the wipers go faster (shorter interval) the resistance of the switch goes _down_, then I can put a resistor in parallel with the rheostat to move the range up again.

The question is, does anyone know which way it goes? i.e. does the resistance increase or decrease when you turn the knob to make the wipers go faster.

I realize that I could just pull my own switch, but I don't want to do that if I'm completely out to lunch with this idea... which is entirely possible.

Thanks!
