Solera should be Lippert
http://www.lci1.com/solera-power-awningIf it was wet, then it sounds like moisture was the problem this time.
sometimes, being just a tad wet, can add enough weight to the fabric .
Yes, the switches could be a problem . Imo, the switch quality is on par with the motor and wiring. The connections as well.
I know it sounds crazy, but i do not use mine. I bring along my 12x12 free standing for short stays or for longer stays, tarp my site and cover 1/2 the TT and 1/2 the site.
( I wish it didn't have to be that way, but i just dont feel comfortable using it )
