Hi. Just hooked up my Airstream for the first time, and my trailer turn signals are not working. Went to my RV mechanic who had a device that plugs into the truck and tells if the proper signal is being sent to the trailer. The truck failed that test. He then jumped the trailer cable and was able to get the trailer lights to work properly. As a third test, I hooked the trailer up to my old truck, and everything worked perfect. So clearly an issue with new truck. Found fuse for trailer turn signal lights, and continuity test showed it was fine. Trailer lights are just standard incandescent not LED. Any ideas? I am puzzled. Will take to dealer if I can’t figure out. Thanks for your help.
