Not my info but if fixed my intermittent wiper issues. I had one intermittent position that worked sometimes and only low/high after that. I took 15 min. and did what this link says and they work perfectly now!

Hope it helps someone!

Ford F150 Wiper Fix Procedures

 

Thanks. I knew of that fix but never saw a detailed writeup. I may do it tommorow.

 

Thanks for the link. On my list of things to do. I have couple of positions on my intermittent wiper that are intermittent.

 

Finally my wipers will work in all the intermittent positions! I've been meaning to find a fix for this. Now I just need to find the root cause of my intermittent blinkers. Therears always work but fronts and the blinking light on the dash is hit and miss and sometimes the headlights will turn off when you turn the blinkers on until you jostle blinker lever. I think I need to take the steering column cover off and clean all the contacts in there.
