I need some help chasing down an electrial issue.
It's an 2005 truck.
For some reason I noticed today just left turn signal of my trailer lights does not work, the tail lamps and the right turn work just fine.
Checking at the trailer plug on the truck, the pin for the left signal is not getting power, any ideas where to start looking?

There is a separate fuse for the trailer TS (both R&L) and tail lights on these trucks.. look inside the fuse box cover for a layout on the fuses (You might need a a magnifying glass).

I had the same thing happen last year. It is prob the computer that is the fusebox. It is 450.00

Very good possably it is the TPIM. Some times they can reflash the computer some times they cant. when you get it fixed I suggest that you put a MODULITE in.

I wonder if this applies...

I agree with Colo River Ram. Check the fuses. I had a couple of them blow after one of my boys put a beer bottle cap in the trailer receptacle.
