Trailer Electrical gremlin

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?

The LTTRLR and RTTRLR fuses are in the IP fuse block on the left side of the dash.

LOL! yesterday I traced "no running lights on the trailer" all the way up the wire harness to the blown fuse under the hood :soapbox: on my RAM. Factory tow package, who new...:shhh:
