I hope somebody here can help me out. I have an 05 Yukon Denali XL with the factory tow package. The right turn signal for the trailer wiring is not working. The turn signal on the truck works just fine. I took a test light to the trailer connector and there was no power. Thinking it might be some corrosion in the connector I cut off some insulation from the wire just before the connector and still had nothing. Is there a relay somewhere that I could check? Any other suggestions?
Thanks for your help.
