Check the fuse first.
How do I locate the heater blend door actuator in a Ford f150 pickup
The bulbs on trailer look good.Lights on truck work.Might be ground not sure.Looks ok.
It has a separate fuse .I bet you have a trailer connection. The correct fuse is noted in the owners manual.
I am having trouble finding the fuel pressure relief valve on my 1997 F150 pickup.
Does it have trailer light wiring also? check that too.
It's the number 14 Fuse.
It's not a fuse. It is a flasher relay that operates either the signal lights or the emergency 4 way lights.
most times it is the trailer plug on back of truck
1998 ford f150 5.4 liter v8 triton 4x4 20 amp fuse is not blown but has no power to it for the trailer stop & turn but has running lights
Yes you will have to order a chilton book from the manufacturer, or find a salvage yard nearby and they can tell you exactly how from experience.
Check the trailer light connections.
Help!!! I'm looking to add a connection to the rear of my 94 F-150 pickup to connect trailer lights...I need wiring diagram to determine what hooks where...can you assist? You can get a tester and turn on tail lights till your probe finds that one. mark it and then do left turn signal light and then right till you find the wire it is. or go to walmart and buy a plug in adapter and plug in to it and no guess work.
