Hi Barney! Had ALL the stuff replaced (I THINK I got the kits from you...maybe? Approx 2011) They worked GREAT for 2 1/2 summers (I don't drive it much, MAYBE 1000 m a year, and seldom at night, hence the "30 uses" statement. I haven't looked it over (not much to "see", as it won't raise), but I'm HOPING it's simply stuck in a way that's simple to remedy. What I'd like to hear is there are a couple (at least one) thing(s) to look for (assuming this has happened to other owners)....???? To be clear, it's just one, so it's a "winker" right now.
