Low beams not working

Please help! My low beams don't work. Could it be the switch or something else? My fuses seam to be fine. Also my overdrive button quit working could they be related?

No solutions huh. Well today I have gone through the fuse block the multiswitch the bright stalk some where I seem to loose it between the stalk on the steering wheel and the fuse block under the hood. Also fixed the overdrive cancel hoping it would magically solve my (I read somewhere on here that fixing the wire might cure it mine was rubbed through but it didn't fix the lights).

Not sure where to go from here. Any body know where the wire comes through the fire wall? there are three or four power blocks on the fire wall. What one has the low beams going through it?

Do your high beams work? I recently had an issue with my tail lights, the blinker & brake portion of the lights quit while the night time driving lights still worked. All that needed done was to replace the bulbs, apparently the bulbs have internal fuses and these had blown causing the problem. Had it fixed for about $8 and a half hour of my time. Perhaps you just need to purchase some new bulbs for you head lights?

Thanks. But I don't think it is my bulbs it happened last winter. Drove home with brights on. Pulled in put it in park and they came back on. Now low beams don't work at all. I originally thought moisture (I do live on the Oregon Coast). But now just thinking wear and tear I do have 245,000 miles.

So far I know I have power at switch. I have power at the multi switch Red and Yellow wire going in and out. From there I lose the juice from multi switch to the fuse block under the hood. If I bypass the fuse with a jumper wire to the light side of low beam fuse the lights come on. So I know the low beams work. I even pulled the bolted power blocks on the fire wall.

Maybe I am missing something? Could it still be one of the switches? Is there a relay? Could be a bare wire but that's a spaghetti factory I really don't want to get into

My old truck did this and I unplugged the multi function switch to put a test light to it got power plugged it back in and they worked. was just a dirty connection, may want to look into this. other than that I know fords over load multi function switches and they go out quiet a bit.

My dad had a similar problem with his Danger Ranger years ago... First no low beams, then eventually no lows or highs. Ended up being the multi-function switch (same switch on Rangers as our trucks). It's not rare for one to go out.
