We have a 2013 Bounder 35K. We've been towing for years with no issues. We always do a safety check before we pull out which includes checking all lights on the RV and the car. The last time we hooked the car up we had no left turn signal or brake light on the car. Is there a way to test to see if the issue is the output from the RV plug, the wire connecting the vehicles, or the input to the car. The signals and lights work fine on the car when not attached to the RV. I'm sure it is one of the plugs on a vehicle. I'm just not sure which one to replace.
