Trailer adapter - no tail lights?

[ahelbling33]

Hello, my 2009 Tahoe Hybrid has issues concerning the tail lights/trailer running lights. I am using the adapter as shown in link below, but the LED for tail lights never lights up and thus my running lights on my trailer don't work either. (I have tried 3 different adapters) Any ideas?

Same Problem

I have a 2007 Tahoe, brake and turn signals work but when I have the headlights on I have nothing. Mine are not LED but thought it was my trailer lights and bought a new set and still have the same problem.

bling33 Have you checked the fuses? You should have a fuse in the engine compartment fuse box label TRLR PRK
