Water Pump not working

Finally getting the motorhome ready for a trip this year (late start) and dewinterized, but the water pump isn't working. Basically I flip the switch and the switch doesn't light up, and the pump doesn't kick on. Flipping any of the switches doesn't work; none light up.

Where can I find the fuse to this thing, and what does it look like?

Or is my relay dead?

Help!


Thanks.

    The fuse is on the dc fuse panel
    In my 95 Bounder it also powers the bathroom vent fans
    Check your house dc fuse panel for blown fuse
    If all fuses are good, then chances are good the water pump relay module is bad
    I just replaced mine, got it on Amazon

    So just went out to find the fuse and the relay. All 12V systems working. Hit the water pump switch a few times (did that last night, too), and the light came on and it started working. I have a new relay on order; mine may be on the way out. All wires/connections that I could see looked fine.

    Most likely you have a momentary switch that is sticking in the closed position. That will make all the other switches non functional. If the problem reoccurs, start disconnecting the switches one at a time until the problem goes away. The Intellitec monoplex water pump controller rarely fails.
