No high beams
I apologize in advance if this has been covered and my feeble search skills have failed me. I have messed with this long enough and now seek the expertise available on this forum.
Truck: 1997 F150 4x4 XLT 4.6L
Problem: My high beams are not working. Low beams and foglights are working correctly.
Steps Taken: (not neccessarily in this order)

Truck: 1997 F150 4x4 XLT 4.6L
Problem: My high beams are not working. Low beams and foglights are working correctly.
Steps Taken: (not neccessarily in this order)
- checked lamps = ok
- replaced multifunction switch (also to fix the infamous wiper problems)
- checked voltage to fuse 16 = 13 volts ok
- checked fuse = missing?
- fuse 16 was missing. I attempted to put in a new 20A fuse but it will not stay in the panel. Closer inspection reveals that while I can see pin 1, pin2 is no where in sight. I looks like this spot was never in use. Pin 1 is off to the right side instead of the space instead of in the bottom like all the other fuse spots.

to begin with there is no fuse in the head lite circuit
only parking, turn, brake, ect.
if you have low beams then the head lite switch is working
next in line is the dimmer switch aka multi function switch
check for the hot from the headlite switch then thru the
dimmer switch part and out to either the high or low beams
check your plug connection and verify it is fully seated
only parking, turn, brake, ect.

I just replaced the multifunction switch today and I know the connections are good. Wipers, turn signals, hazards and the washer pump all work correctly. The high beams did not work with the oem switch either.
A little more description of what happens is maybe in order. If I have the low beams on and turn on the high beams, I have no headlights at all until I shut off the highs. If I run the low beams and foglights, they both shut off when the high beam switch is engaged.
I will put my meter on the high beam connector and the lamp switch in the dash and report back. However, I am very suspicious of that empty spot on my fuse panel.

They only had one fuse for the Headlights.

The high beam output of the MFS DOES go to CJB Fuse F16, then to the high beams and the in-cluster indicator.
I suspect that if the OP drops the fusebox and looks at the rear, he'll find that one pin of the F16 socket has been pushed out the back.
