2000 Le Sabre custom wipers

[Eric Wettschreck]

Ok, this one is kind of weird.

I sometimes carpool with a fella that has a 2000 Le Sabre custom. Today it was raining and that's when I noticed this. He turned his wipers to "Intermittent." No big deal, right?

As it rained harder, the wipers went faster. When the rain slowed down the wipers slowed down. I mentioned this to the fella who owns the car and he said he noticed it too but didn't know if this was supposed to happen. He's wondering if there is a problem with his wipers.

So my dumb question is, is this supposed to happen? If so, is there some type of sensor that actually sees how hard it's raining and sends signal to the computer to adjust accordingly, or am I on crack?

You're ok Eric, the Buick's use a rain sensor to change the speeds. Not positive but it used to be on the back side of the rear view mirror.
