Hi Im new. Name is Barry

Have a 97 F150 with no high beams. FTP does nothing when lever is pulled back, stays on low beams. When lever is pushed forward for high beams I loose both H and L beams. Tested all fuses and relays with meter and all are good. Tested MFS with meter and have power to L and to H when in the correct positions. When lever is pushed forward for high beams the switch cuts power to the low beams, retains power to H beams but no power to headlights. Not sure if this could be a ground issue or if it's in the MFS. Also there is no dash indicator for H beams.
Any help would be appreciated

Both bulbs are good? Probably not a ground since you have low beams.

I can't remember that one off the top of my head. I want to say theres a relay and a fuse involved for highbeams

ETA: Fuse 16 (20A) and no relay

are you getting the indicator on the dash? if you aren't getting the dash icon, you know the issue is from S114 and above


looked in this thread. second set of links for diagrams
