Low beams not working on 2004 Toyota Tacoma

Are the L.E.D. light bulbs the right way around in their sockets???
The ground side of the L.E.D. must go to ground!!!!!
If they are grounded the right way then all the lights will work.
Normal bulbs will work which ever way they are put in.
L.E.D. bulbs will not!!!!

Geoff

Ck the relay switch the high one to the low they are the same also I believe they are fused in the one fuse box under the hood behind the battery

It can be faulty low beam lamp or its connection issue for low beam lamps.

There are few solved helps links with proper solution to troubleshoot these issues.I suggest you to refer the links below.Click the link:----

These trucks are known for bad multifuction switches.
the switch that i talk of is the signal switch , the handle is the switch, it bolts to side of steering column . this switch controls the signals and the headlights and high /low beams. the other thing is the headlight switch connector, the connector some times goes bad and starts to melt or just comes out of the connector. you will need to remove the cover to steering column, the screws are located under the bottom cover in holes. remove cover and check connector and then test for power if you have power going into switch but not coming out then switch is bad.

the last thing is to make sure the bulbs are good , make sure the headlight bulbs are good , and also the driving light bulbs, test for power at the connectors to those lights to.
You will need to do a little testing to find the problem.

I would focus on the connections going to that head light for the low beam. I agree, it is not the switch, otherwise other side low beam would not be working. It is most likely bad bulb inlet( if it i separated bulbs for high and low) or it is the connection going to the low beam that operates it. Hope this helps. Don't waste your time on switch, it is not that.

CHECK THE BULBS FIRST! TRY REPLACING WITH A NEA ONE ON ONE SIDE, AND TURN LIGHTS ON, IF YOUR LOW BEAM LITES UP, REPLACE THE OTHER ONE! IF NOT THERE COULD BE A WIRING PROBLEM TO THE LOW BEAMS

If there is power there, then it has to be the bulbs. The trouble that most people have is, they don't see how both bulbs could burn out at once... and they're right. They don't. But you see vehicles with one headlight all the time. They don't know it unless you tell them or they happen to see it themselves. Then the second light burns out, and they think it's a major catastrophe, when in fact, it's just bulbs. The high beam still works because the bulb is double filament. The only other thing it can be is the dimmer switch, and since you switched it to high, it appears to be working. However, if it's not bulbs, it still could be the switch.

sounds like it may be the lever itself on the wheel for turnsignals etc. otherwise use a test light to determine where power begins and ends at the switch by removing it a good ground and start testing by switching from hi beam to low beam this will let you know if i am correct with my determination

on toyota the switch they go bad are just the low beam bulbs blew out

are the high beam headlight bulbs blown? if not replace highbeam relay or fuses
