2020 2108DS rear lights don't work red marker,turn, stop. The front yellow lights work. Does anyone know ehere I can find a wiring diagram?

Winnebago has full wiring diagrams online at www.winnebagoind.com. Click on Resources > Service > Scroll down to Wiring Diagrams.

One side note - I had a similar problem on a SOB (some other brand) RV a few years ago. I searched out all of my fuses, found a replacement relay/switch and that didn't fix the issue. Finally, I took off the plastic lens and looked at the bulb. I was sure it couldn't be the bulb because it was both lights. But sure enough it was - both bulbs burned out from water intrusion (they were incandescent bulbs). I doubt this applies to you - but sometimes it's the simplest fixes that are over looked.

Thank you. It seems that they only have Wiring Diagrams for Motorized units.

Check and clean your 7 pin plug.

I called the Winniebago Towables phone number on the website, the person sent me (email with PDF attachment) the diagrams for my 2306BHS, she said they don't post them online.

I went to the Winnebago site and requested a wiring diagram and they emailed me the PDF. I discovered that the front and rear lights use a different ground connection. I confirmed loss of ground in the rear. I removed the right tail light and ran a new ground wire to the chaises and that solved my problem.
Thanks for all of the subjections and assistance.

I replaced ours with these LED lights. Nice easy upgrade.
