Hi, I'm new to this site and hope someone can guide me to the right area or is able to help fix my problem. I have a 2001 Ram 2500 5.9L Diesel and it's been a champ up until this fall when I crossed the 100,000 mile marker. At first, my low beam headlights seemed to quit working, then they would be OK.
When they would not work, I could switch over to the high beams and then back, usually it would fix the problem. I looked at a wiring diagram for the multifunction switch and figured it must just be a bad switch. Got a new multifunction switch from AutoZone ($59) and installed it with no problems. The lowbeams seemed to work normal again, but for just a day. Has anyone else had this issue and what was the fix? I've seen where someone said it was a loose cable, but which one? It appears that the controls to the headlights are all "Ground" related. Is it possible to hardwire a new ground with a relay and have the lowbeams on all the time, even when the highbeams are triggered? Thanks, looking forward to many great responses.

 

What switch did you replace? the signal lights/high low beam switch? I'd be willing to bet that its yer headlight switch itself. I know of at least 3 or 4 dodges that had to have the headlight switch replaced because of the same problems.

 

Yep, pullout headlight switch. A very common problem.

I am having the same problem.. my low beams dont work at all but my high beams do.. i have changed out the bulbs and the pull out switch.. and nothin worked.. still no low beams.. i dont know where else to look???????

 

Except on a 1999 and newer (maybe even 1998), it won't be a pull out type switch. It'll be a rotary type. JFYI. But the fix is the same for either switch, replacement.

Did you replace the multifunction switch on the steering column?

 

Jason, in 98 they are still the pullout type

 

hey guys i just found a thread with this info.. it could be very helpful!!!!!
