Troubleshooting No Stop/Turn Signals on 7-Way on 2013 Winnebago Itasca SunCruiser

Question:

I have no turn signals or brake lights on my tow dolly that I just bought. Im towing it with my 2013 winnebago suncruiser. I have power to the receptacle and power to the running lights, but nothing to the right and left turn signal or brake lights. Ive had the tow dolly checked out, and checks out OK. Can not find the fuses for the turn signals. The manual tells me where there supposed to be, but, those particular fuses are not there. Could it be the receptacle could be bad? and would you happen to know where the turn signal fuses are?

If fuses are missing from the tow connector circuits on your 2013 Winnebago Itasca SunCruiser then this is the most likely cause for you not having left and right stop and turn signals for your tow dolly. These left and right signals are carried on two separate circuits, each with its own fuse. I reviewed an online manual for the SunCrusier but the online version does not include a fuse panel diagram. The manual does indicate that the RV comes equipped with a fully-wired 7-way.

Based on my research some models will have a fuse panel on the left side of the dash. If you cannot locate it you can check with Winnebago using the RV's VIN.

It is also possible that there could be damage to the wiring leading to the 7-way or corrosion inside the connector that is preventing the stop/turn signals from reaching the pins on the 7-way. You can inspect the trailer connector and the wiring leading to it for any signs of damage or corrosion.
