2006 Dodge Ram tipm issue and fix no low beam

If your high beams work and your low beams do not work... try changing the light bulbs first. The low beams can burn out and the high beams still work.

When you switch from High to Low beams, do the lights go out, or continue, in the "High" beam position??? If they go go, the transfer switch, that changes the high/low beam mode is working. The most likely problem, is that the Low Beam filaments are both burned out. Some, on original equipment, never changed, can burn out within days/weeks of each other. Could be that.

Are the bulbs good?

If your low and high beams are on the same bulb, then the low beam elements have blown even though the high beam still works, you need two new bulbs.

Your dimmer switch is bad (lever used to flip between hi/low beams) they're only plastic and they go bad. Before you change check fuses, buy I highly suspect dimmer switch.

did you check for a relay in your fuse panel? there should be a relay that controls your low beams and one for your high beams. check for that and then if high beams are working swap it with low beam relay. if your problem switches to low beams working and high beams not working replace the bad relay.

DID YOU CHECK THE BULBS?

1. Open the hood.
2. Remove Grille.
3. Remove the 2 retainers on back of headlamp assembly and remove the headlamp from the sheet metal panel.
