rear stabilizer jacks

We have a 2010 Sundance 2900MK which we have been very pleased with and has over 30,000 in two seasons. Recently we discovered the rear stabilizer jacks do not operate using the 12 volt switch. I don't seem to find an in-line fuse for the stabilizer motor like the front jacks. Any suggestions? Thank you for your help.

Have you checked the fuse panel in the coach? It also might controlled by a circuit breaker in the front compartment. If you have a 12V test light...start at the motor and work your way back to see where you are loosing power. I had some wires terminals at the switch that were corroded...you might look at that.
