My 03 H2 has a problem with the brake lights for the trailer...
The brake/turn lights work fine ON the truck, but the left side lights on the trailer/ 7 pin connector don't work.

I tried 2 separate trailers and checked voltage at the connector. The left side brake/turn lights have no voltage...

I could not find a fuse for the trailer lights...

Any clues?
