Have Ford Questions? Ask a Mechanic for Answers ASAP
Welcome, I'm Chris (aka Moose), my normal schedule online is around lunch and after dinner past midnight.
We are allowed to help diagnose and fix one issue per question. Which issue do you want my help with?
The trucks front and rear parking lights stay on, correct?
When you remove fuse 38 the trucks parking lights now turn off, correct?
Has someone been altering the wiring on this vehicle?
All these lights are on the same circuit:
I ask because you said the front parking lights work correct when turned on and off but the rear lamps stay on all the time.
Are you sure it is the rear parking lights on and not the brake lights?
Okay that means it does have altered wiring. Ford does not sale trucks with flat beds and headache racks. Someone installed that bed on this truck. Someone has spliced into wiring for these lights. Can you see where whom ever has spliced into the trucks wire harness for the flat bed?
Ford diagrams went down 5 minutes ago for whatever reason. I really need them back up to accurately go through this circuit with you.
I have worked at 3 Ford dealers and we never install flat beds. The cab and chassis truck comes off the semi then the truck is sent off to a company that installs the different bed options. Ford only allows Ford dealers to install Ford products. I doubt the dealer installed the bed unless you physically watched them do it. Can you see where whom ever has spliced into the trucks wire harness for the flat bed?
Ford diagrams are back up, would you like me to to show and explain the issue I am trying to relay through them?
Hello again Chris here,
