The 12 volt lights down the center of living area does not work.

do you have the wrench that u can manually crank it out? if not try to bypass the switch with a 12 volt power source directly to the motor. take a a 12 volt battery and two leads and tap in to the motor. if that does not work. the motor could be bad.

there is a momentary three way two pole rocker switch used to activate the linier motors that move the slide out. the most commin problem is they use a switch that dosen't have a high enough amp rating and the contacts burn out quickly. it is very importent to release the switch immediatly after the slide stops motion going in or out or these switches burn out very fast.

Check to ensure nothing is blocking the slideout, its path or the gears of the motor. If you don't see a dimming of the lights when you push the retraction button or don't hear any motor noise check the fuse for the slideout motor. If all else fails there should be a manual slide retraction option somewhere that allows you to retract the slideout using a crank or a power drill. Check the owner's manual.

Check to be sure there is no debris in that area and that the rubber weather stripping isn't loose or stuck. Oftentimes tree leaves and small branches can fall and block the area, stopping the slideout from closing completely.

BINGO - try looking for the GFI - maybe the bathroom - that could very well be your problem.

Are you sure that the system is 24v? Most RV's these days are 12v and may have two batteries that are wired parallel. If they have been rewired in series you have increased the voltage to 24v and that is why the bulbs are not lasting and everything else is failing. To wire the batteries in parallel, negative will be wired to negative and on to the negative or ground lead. The positive will be wired to the positive and on to the positive lead. If the battery is wired from ground to negative and from positive of same battery to negative of the next battery and positive of second battery to positive of the system then it is wired in series and that would be wrong.

Not sure what kind of trailer you have, but the fuses should be behind a metal cover - for mine, its located under the refrigerator. When you open it, you will see all of the fuses. Hopefully, they are labeled, but don't bet on it. Use a meter to check the fuses - put the meter tip on each side of the fuse, with the meter on volts. If you read 12 - 14 volts, the fuse is blown. A good fuse will not show any voltage.

If you can't find the fuse box, when you have the camper plugged into AC, turn on all the lights - the fan that cools the inverter should come on - follow that sound and you will find the fuses. Good Luck

use a meter to check the sockets for voltage either 110acv or, 12v dcv
if dcv it's is your batteries or inverter not supplying power check with a meter set on dc volts; if ac check your circuit breakers with a meter set for ac volts if these are fine then replace switches

Remove the cover. Remove old bulb. Replace new bulb. Replace cover.
