06 F150 5.4. The headlights were working perfectly a day ago highs, lows, drls, and were also functioning in auto position. Now my auto is not doing anything (including illuminating the cluster) as well as not turning on any lights. I tried turning the selector switch to the manual position and the only thing coming on is my tail lights and parking bulbs. I've tested all the fuses and everything checks out. Anyone have an idea as to whats going on? All expertise is greatly appreciated.

 

have you looked at your fuses thats where i'd start.

 

Yeah they are all good.

 

Check Fuse 25. Do the high beams work?

 

No, high beams, no low beams

 

Could be a bad multifunction switch.

 

any way to by pass it?

 

yes, but its not practical, especially if you need to ask.

sounds like you need a new multifunction switch.
