Trailer plug-Prking/tail lites inoperative...

[yukon2002]

Trailer plug-Prking/tail lites inoperative. All fuses are fine, brakes and turn signals are working. No power at trailer plug for running lights and tail lights. Is there a relay or something? I tow my boat every other weekend and this morning, no lights. I'm an electrician and I'm looking for the simple thing, but need to know where. I have a factory harness and would assume it's not a wiring problem, since I've never had any issues before.

I had a similar problem, took the dealer 3 times to fix it.

Thanks for the response, I guess I'll take it in to the dealer.
