Cars High Beams not working, Low Beams Do Work

Sometimes you will lose a Hi-Beam light and not really notice until the other burns out. Best replace both bulbs whether they are seperate or an integrated hi-low beam bulb and if they are seperate replace the low beam at the same time. Also go for the bulbs that give you the extra range when you do replace them..

Did further research, they are seperate bulbs, get the Hi-Beams and Low-Beams at the same time and replace them.

Are you absolutely sure that there are not separate fuses for high beam and low beam? Ford does have a habit of doing that.

Otherwise I suspect that dawgofwar10 may be on the right track.

FWIW, had two Broncos, '70 and '71 that both had problems with a relay in the headlight system. Use high-beams for about 2 minutes and they'd go away. Switch back to low and everything was fine. High-beams again and problem repeated itself. Never got around to R&R the relays, as the truck never got driven that much at night at speeds where high-beams were necessary.
You might replace the relay(s) and look for corrosion that could cause heat to build up.
HTH.

That was a common old Ford issue - the circuit breaker in the headlight switch would go bad and play games.

Completely different from the OP's vehicle. Nearly everything is computer controlled these days. 2013 - 2014 had a myriad of electrical issues to include faulty fuses and body control module issues. Have the problem checked before throwing parts at it. :)

Oddly my other SIL (the one I 'm never alone with) is looking @ one of those to replace her older little ford sedan (2007-8 Vignale? I can get in but it's a choir - nice leather etc for a mini car) . Please post the resolution or if it's worse than you thought .

You could be saving me untold whining and anguish.

Ok Griz, this is the scoop on that car. The model I have was made in Europe, they are not being made anymore (at least not there, maybe? ) according to Alphaman.
The ones left are still selling at a premium.
That being said, it does seem to be a headlamp (bulb) issue.
But. To replace said bulbs, the whole bumper has to come off.

Sounds kind of like the 1967 Chevy Biscayne I had. You had to remove the right front fender to replace the heater coil.

Engineers: "I have a great idea. Let's put the heater coil on a temporary stand and build the car around it."

I hear you. Our 2009 GMC pickup is running on 7 cylinders... we know it needs a new spark plug and wire. But the job is SUCH a PITA, none of the men folk want to do it. Considering they've rebuilt 2 ATVs, 1 Ford 3000 tractor engine and done several brake jobs on the vehicles this year, it's not they aren't familiar with the work...

Of course, the fact it's getting 3 mpg better than normal might be a factor!

Over the last 45 years I've had “a few” cars. The headlight problems I had were one of these…

- headlight switch in the dash

- Hi/Lo switch on the floor

- ground wire from one of the lights

- fuse (either round, or blade)

- but, first make sure the light itself ain't bad. Test with a 12v power lead, and a ground (a cheap set of jumper cables will work…)

Good luck!

What’s the word? Thunderbird… Anywho let’s get to the discussion at hand, did you get the bulbs yet and have installed them? And if you did please let us know, else we will evolve into a Tulip discussion before it is all said and done….

Been there done that, 12 hour days 6 days a week, then taking care of household stuff on Sunday. Did it for 23 years, now my age is keeping me from planting Tulips, no less all the other things around the house!!!

Had that problem with a 2019 F250. It was a computer module and it cost 1700 to fix it, mostly labor from them diagnosing the problem.
