Strange Winshield Wiper Operation

[dond13]

I normally use the 'Auto' position for the Wipers, but yesterday I was driving in fairly heavy rain and used the 'Lo' and 'Hi' positions. They worked as expected while I was driving in normal traffic. When I got on the highway and was driving 65 MPH, they were opposite. When in the 'Lo' position, the wiper speed was fast and when I switched to the 'Hi' position, they slowed down. I tried it several times and it was consistent.

When I got off the Freeway and slowed down for traffic, the 'Lo' and 'Hi' worked correctly. Back on the Freeway, they worked in reverse again. I can't find anything in the manual that would explain this and I will mention it at the next service. I didn't experiment to find out what speed cause the reversal.

Am I missing something? Has anyone else seen this behavior with their Wipers? Any explanations?

dond13,
Yes, I actually had a weird experience with my wipers while in the auto mode. Mine was a little different though. It started to rain lightly and the slow/fast setting was on fast so I dialed it down to slow. That worked briefly when from nowhere the wipers started to go so fast I thought they were gonna fly of the car. I turned the on the normal setting then later it started to rain harder so I went back to auto and the wipers set to fast they went slow. Good news is since then they seem to be working correctly. But I do think there is a possible glitch in the auto mode. When I go to the dealership for next service I will tell them about it and maybe they will find something.
