Title: F150 door lock issue/ trailer wiring
Post by: Angry Perch on September 20, 2016, 11:18:12 AM

2012 F-150 crew cab. Right rear passenger door lock gets stuck here and there. Power lock won't unlock it, so I have to yank it up manually. Hard enough to pull that my 12 year old daughter can't do it. Just wondering if it might be a common / quick fix or if it needs to hit the shop.

Also, factory trailer wiring, all of a sudden only running lights work, but no signals, brakes, hazards.

Trailer could be a few things, I'm guessing you've tried checking the connection, being that new they have separate fuses for the trailer (info in owners manual). Trailer been jackknifed recently? Seen a lot where the wires are pulled free in the trailer plug but all looks well

Trailer could be the bulbs maybe? Replace with the 1157 bulb?

Thanks, I'll check this out. As for the lights, it's definitely not the trailer. Using test light at plug on truck.
