Hi Ram People,

When I started my '03 Ram 3500 diesel after it being parked up over Winter, I've found that both my front signal lights / indicators have stopped working, along with one of my rear indicators, left low beam & right high beam headlights.


I read on a quick Google search that it might be the steering column multi function switch (indicators / headlight low & high beam / windscreen wipers).


I'm in the process of getting to the multi switch to see if it's worn, but wondered if it might be anything else.


These trucks don't seem to have any fuses or relays for the headlights or inductors.


The bulbs seem to be OK in the headlight cluster, and my voltmeter says there's no voltage at either the headlight bulb socket or the indicator socket, once the bulbs are removed.


When my Hazard light switch is on, I still only get my rear right indicator coming on.


Any suggesting would be greatly appreciated.


Thank you.

Regards,

Daf Tekno

Check your wiring harness. Some rodents may have nested in the truck over the winter and they like to chew on the wiring.

Your fuses and relays are under the hood up front on the right hand side. A black plastic cover with a single screw knob on top. The left signals are separately fused from the right side. I'd be checking those first since you say you don't have any power to the lights. After that, I'd be looking for rodent damage or something not grounding. Good luck,
