So I had just switch out my wiper Linkage. The way I did it was unbolted the wiper arms, then the splined parts from the under side of the cowl. Unbolted the Wiper motor leaving the linkage connected at the motor and pulled everything out as an assembly. switch the linkage then back in and connected. Now I am not sure if this is when this happened but now the Hi speed just stops. The Combo switch is new did the swap from the FAQ. Everything looks good on that end. I saw another post on this doing a search and it was suggested to try the Hi speed with the blades in the up position (not touching the Glass) I had the same issue. Am I missing a ground that I didn't notice when reassembling it?
