Anyone know why my truck is not sending brake on/off, left/right turn signals, and hazard lights power to my trailer? The running lights work however. The trailer is not the problem because it works with other trucks and my truck won't work with other trailers. The fuses all look ok. Maybe a relay? bad ground?

Thanks, Dave

I know on my 2000 model, there were relays up under the hood that are not installed when you buy the truck. Maybe there's a trailer relay that just hasn't been installed yet? just a thought.

Also my 02 has a seperate fuse for the trailer lights. Not sure of the number, but it is in the fuse box under the dash. That was my problem. post up what fixes it.

Blown fuse!

I found it finally, I was looking for a blown fuse in the wrong fuse box, the blown one was under the hood and not in the cab.

Nice find, I do not have any trailer fuses under the hood. I tried to get the 06 wiring diagram, but the ford tech service website will not let me in right now.
