A/C blower and high beams?!?!
I lost my A/C fan in the cab and my High beams at the same time. Fan runs when jumped at the relay. Headligts work but no highbeams. All fuses have been checked. Had a poor tailor light job performed a few days before. I could really use a wiring diagram for the rear harness and some help diagnosing this.
97 f150 288k miles runs like a champ. No options other than A/C. 4.6L

Welcome to FTE zydeco76! 
Does the fan run at all, maybe high speed only? If that is the case, the blower motor resistor pack is bad. As for the high beams, did you check the bulbs? If the bulbs are good, then the problem is likely in the multifunction switch. I have a wiring diagram on the 2002 model but not on your truck. Good luck!
