Test your batteries, coach and chassis. If they are OK, then it may be your switches.
Mine went out, and were replaced by my dealer. Fortunately, this was under warranty. Which, unfortunately, means I cannot tell you the cost.
My dealer told me the switches were defective, that GS had trouble with them, and that the new ones he installed were much superior to the old. Then again, he did sell me the coach.
