I have a 2016 Tiffin 36LA on Ford F-53 chassis. My running/tail lights on the passenger side are not working. Brake lights and turn signals work fine. Everything on the drivers side works fine. I have changed the bulbs - didn’t help. Checked fuse on the Ford distribution box - that fuse okay. I am thinking Tiffin installed these lights so might have a separate fuse somewhere? Any suggestions would be appreciated.
Problem solved - I think. My neighbor in the campground came over to help. I told him I had checked fuses, bulbs and voltage to sockets. So while he was there we checked the sockets for voltage again and they had voltage. I put a bulb in and wiggled it just right and it came on. I pulled the bulb and sure enough one of the contacts in the socket had broke. I didn’t realize I needed to check both contacts - when I checked that side no voltage. The crazy part when I checked the other socket and bulb the contact on my other socket was also bad. So both tail light socket contacts went bad at the same time (part of the contact broke off) but the turn signal and brake lights are still working ( they apparently work off the side of the socket that is still intact).
Had similar issues with original tailight assemblies. Fleetwood used Ford tailight assemblies. I purchased after-market sockets fro O'Reilly auto parts.

If all sockets have current then you have a bad ground. Can you easily pull the light fixtures off and see what's behind them?
Bingo. SWAP the Drivers side BULB to the INOP Pass side socket. IF it does NOT work but the Turn and Brake do, then the socket is bad(ground connection in the socket is bad) and you have to replace the socket. I believe you can get replacement sockets in the "help" section of auto parts stores like Auto Zone. Doug
PS if the Brake and turn signal work, then the ground TO THE SOCKET assbly is there, just not to the Running light pin in the socket.

You are not looking for daytime lights. You need to look in owner's manual or this manual 64-75 Many are wired into the trailer tow fuses. Test all the fuses with test lamp is the easiest.
There are 2 fuse boxes for Ford. The one outside by the engine oil fill and the one inside by the emergency brake pedal on the firewall. There is a fuse for each light. The sockets are part of the Ford wire assbly. The wire harness's GOING TO all 4 outside corner lights are FORD harness also. This is where a voltmeter or 12 volt test light comes in handy. Instead of just replacing a bulb, you make sure you have power AND ground to the bulb socket. Doug
Yes, installed by Tiffin. Ford has two fuse blocks. One under dash and other under hood/doghouse. Does the rig have lamp outage function? Splice under hood/doghouse?
