Yesterday we had a summer-like sunny warm day and I'm thinking, oh yeah time to let the rays back thru the roof. So I push the s/r button and it proceeds to open about 2 inches and stops :? , I push it again, same thing , 2 inches and stops. I ended up having to open it 2 inches at a time till it was fully open, same to close it. It did this all day, from one kid's soccer game to the next! Anyway, this mornings another nice day, so I trty it on the way into work, surprise it works fine. Has anyone else experienced this anomaly?
