A possibility is the multifunction switch or the tipm being bad. check the wt/lg wire in the left headlamp assembly and the wt/tan wire in the right assembly for power

2005 dodge ram 1500 high beams one light works, low beams the other light works.


The dimmer switch is the first thing that came to mind. Could trace your wires starting from your lights, and look to see if you could find a ground location. Relay for the lights?

I have a 2001 dodge ram 1500. does anyone know anything about the headlight wiring?I would like to know how it works. Currently , i know the violet wire is 12v constant and the vt/wht wire is ground when...


Well, where to start...
First there are 4 different headlamp systems available for 2001 Dodge Ram 1500.

> WITH Daytime Running Lights and WITH Quad Headlamps

> WITH Daytime Running Lights and WITHOUT Quad Headlamps

> WITHOUT Daytime Running Lights and WITH Quad Headlamps

> WITHOUT Daytime Running Lights and WITHOUT Quad Headlamps

So providing you with an EXACT flow chart of what happens depends on which system your truck is equipped with.

However, the general jist of it goes like this:

The Violet wire you mention is your power feed to the bulbs (high beam and low beam elements) from the headlamp fuse (HOT AT ALL TIMES). The dimmer switch basically determines which of the two headlamp elements is going to get grounded to complete the circuit. When the Violet/White wire gets grounded, that is low beam. When the Red/Orange wire gets grounded, that is high beam.

Just a little "Automotive Electrical Systems 101":

Your Headlamps work just like ALL automotive electrical circuits. The power goes from battery POSITIVE to battery NEGATIVE in order to complete the circuit. PERIOD! Every circuit on your vehicle is as simple as that. If you take a closer look at the wiring diagrams, you will see this.

I have no headlights!! parking lights, taillights,and blinkers all work fine. none of my fuses or bulbs are blown


I have a 2004 ram 2500 and all my lights work except for low beams. It is not in the switch, I haver replaced the switch with no change. This is a circuit problem with these dodge pickups. I haven't firgured out what it is but it isn't the switch. and unless the low beams and high beams are fused seperate, it isn't a fuse problem either. i have looked for a fuse and can't even find the fuse for the headlights. Im lost like you!

Left low beam is out on my 2006 dodge ram 1500 4.7 v8 the bulb isnt blown and the high beam works low beam does not


I'd still vote for the bulb being bad. The high and low beams use two different filaments, so unless the bulb is physically broken, it is common for the low beam to be bad whilst the high beam is good.

That's why you see some people driving around with their high beams on -- they don't want to get stopped for a 'light out' citation..

When you take the bulb out to replace it, be sure to look at how it is mounted before removing. You don't want to accidently adjust your headling out of kilter.

good luck

Headlights not working right


Usually headlights have two filaments in them for low and high beam. One of the fillaments may be broken while the other is still intact which is why the low beam works and the high beam doesn't. The solution is to replace the bulb. This should take care of the problem.
