Anyone know what the switch located under the kitchen cupboard located above the sink of a 1999 Citation camper is used for?

check for wires going into the water tank, check under the sink, check under the shower(if fitted)
follow the water line from the tank back and there will be a pump in that hose somewhere

blown fuse check under the hood or under the dash check your manual to find the exact locations

a thermostat does'nt have wire's , it is completely inserted in a housing ,i think you may be talking about temperature sender switch which will have wire's and they should have a connector that corresponds with a connector by the location

Inertia switch for the fuel pump? Ford is the only manufacturers that uses this type of switch.

Simply take a little test of the floors with you to Lowe's or House Depot and request somebody in the color department to help you available. Additionally they have a few colour blends that appear to be well-liked with allot of folks. What I am talking about is they have matched sets of colours that combine together therefore all you must do is purchase the color and you know it'll fit. Hope this can help and best of luck. shopfitters

Great to here it is fixed.

Your fuel pump relay is in the under the hood fuse box and should be marked. If not looking into the fuse box you"ll have two rows of fuses (side by side ) totaling 18 fuses, there are two relay just above the two rows of fuses and the one directly above the fuses is the fuel pump relay. Also you mite want to check your inertia switch and make sure the red center button is depressed ! you"ll find the inertia switch located behind the right hand kick panel (down on the floor inside the vehicle,passengers side ) good luck thanks for using fixya

Is it a slide in camper? and if so there should be jacks that go at the 4 corners above the truck box. you lift the camper up slightly and drive the truck out from under the camper. The jacks could have been removed and stored in the camper under a bench seet in the dinett.

Any place that sells campers can advise you. I would disconnect the water supply line underneath the camper and open all faucets. This will drain the lines. Pour some antifreeze especially designed for this purpose in the toilet and in all sinks. Don't forget to flush the toilet and pour a little in the tank after you turn the water off. This will prevent the traps from freezing.

Just a thought, but it might have a Leisure battery fitted and all the elec's could be run from there, check to see if the second battery is fitted and/or connected
