I looked in my manual but didn't see anything about this.... When I try to use the levelers, I put the rv in park with the engine running and turn on the system. When I press the arrow for the jack I want to extend, the red light by the power button, which had been steady, blinks and the jacks don't move. I'll try it again and again, and eventually after a few minutes, the jacks will extend. It used to be that as soon as I wanted to level it would work, this delay is a new thing. Storing the jacks works as it always did. Any ideas?
