The turn signals, hazard flashers and headlights all run through the multi-function switch in the 2001 Ford F150. If you have an issue with more than one of these systems at the same time, logic would dictate that the multi-function switch is the source of the problem. Located within the steering column, just forward of the steering wheel, the switch is made up of a rectangular switch body, and the turn signal stalk that protrudes from the side of the steering column. Installing a new multi-function switch is a simple repair that requires roughly 15 minutes.
Slip the tip of the trim tool between the top clamshell and the bottom, on the side of the steering column. The clamshell is the half-moon shaped trim that covers the top and bottom of the steering column just in front of the steering wheel.
Pry the clamshell off the column with the trim tool and then set the trim aside. Unplug the wiring pigtail connector from the body of the multi-function switch.
Remove the screw holding the multi-function switch to the steering column using the Phillips screwdriver. Lift the switch out and set it aside.
Lower the new switch into place. Thread the screw in by hand before tightening it until the screw head is flush with the switch body using a Phillips screwdriver.
Plug the wiring pigtail connector into the new multi-function switch. Snap the clamshell trim back into place on the steering column, making sure the hazard switch button clears the hole in the clamshell.
