I am a relatively inexperienced owner of a 2005 Winnebago Sightseer 29R. For some reason there is no power to the control unit of the hydraulic jacks. Not sure what the issue is. Can anyone provide any advice? Which fuse? I am not having any luck.

Thanks in advance for any help/advice.

If it is not truly a power problem it could be low on hydraulic fluid, I had that on my coach. Just sayin'..Fred

You didn't give us clues as to how you know there is no power to the control unit.

There should be a "lock out" on the jacks so that if the rig is not in Park and the parking brakes are not set, the jacks should not work.

There is NO Jack system that will shut OFF the power to the Jack system if low on fluid. Please explain better. You mean the TOUCH pad in the drivers area is dead or the power to the Hydraulic Pump system. The Pump system has a heavy Gauge positive wire where the dash pad uses Ignition power. This should be your operators manual (325 system). Doug

What brand and model or type of levelers do you have? Mine has a fuse at the joystick control panel, another inline fuse at the pump, and yet another under the hood in the power distribution box. I've blown all three at different times all for no apparent reason. I've also lost power when the joystick panel cover had issues. On mine, the power to the main switch runs through a set of spring contacts between the panel cover to the circuit board below. After checking all of the fuses I accidentally found that pushing down on the panel would cause the LED's to come on. Pulled the panel, stretched the springs, and replaced the panel. That corrected the problem....at least for now.
Good luck,
Terry

Just a guess. If sitting in the cold for a long period, the oil could thicken and cause the pump to draw more power and COULD possibly pop a fuse. Again, just a guess.

You would get an Indicator on the Touch Pad if the Brake was not set on his year model. Doug

The RV is in park and the parking brake is set. There is no power to the control unit and the red light on the dash, which indicates that the jacks are down, does not light up. Everything else in the RV appears to be in working order.

As a side note, the RV has been parked for the winter since November. Although I have started the RV at least once a month and let it run for a period of time, it has not moved. Not sure if that has anything to do with it or not.
