Just had an issue in my 2014 where the left rear wouldn't raise on first try. I fiddled with switch, recycled it, and it started working.
I emailed Quadra Tech Support today for the required PM steps. Prompt response. They recommended some dielectric lube in the switches as we as some dry lubricant or teflon spray on the shafts of the cylinders. I'll do that this weekend.
