Headlights wont burn on low beam

Did you actually check the bulb? It may have burned out or the wiring to it may have lost connection. Some of these vehicles actually have a separate fuse for the left and the right headlights.

Check your head light bulbs, your truck has the dual filiment headlight bulbs one per side which does both high beam and low beam, 9007 bulbs.
If the low beam filiments are burned out only the high beam will work.
Also look into finding out if the headlight switch is gone bad.
The headlight module and or drl module maybe defective.

main power issues .. check battery connections.. check fuseable link wires under hood,..check fuses in fusebox for blown fuses and check wiring harnes ground connections especially by the headlights..

See fuse for the headlight low beam or the head light low beam filament is bad change it after testing it on the battery

Hello. Generally when this happens, the high-low beam switch has gone bad and needs to be replaced. If you are handy you can do this your self. Otherwise, any autoelectric repair shop is your best bet. J.

just change your handle switch at the steering all beams will work

If the headlamp burned out it would be more than likely that there is a blown fuse , there is a fuse each for the high and low beams.

What you have sounds like a Headlight SWITCH Problem, You can check the Fuse for them (DOUBTFULL) but its a Large one @ Power distribution Box Under Hood.

Possibly headlight switch

Clyde,

I've been troubleshooting this same problem on a different vehicle this week, and I can give you the steps I'd take.

1. If both sides went out at the same time, the problem is *NOT* likely to be the bulbs.

2. Check the fuses to see if both low beam lights are on the same fuse. Many cars have one fuse for low beam and another for high beam, so both lights out at the same time typically means fuse blown.

3. If the headlights are OK and the fuses are OK, then the problem is *LIKELY* the headlight switch. In my case, AutoZone has one and it can be installed easily; but in your case, that may not be as simple.

Please post your findings or comments.
