My issue is in the intermittent mode- i.e. up one notch. I've been on the highway wanting the wipers to sweep every few seconds, but they'll go from fast to every 5 seconds then back to fast. It's been irritating in the salty spray to have the wipers sweep too often and just smear the partially dry salt around. I know I can go up to low speed and override, but that's not the point. When I want a 2-3 second intermittent, I don't want it alternating between fast and nonexistant.
