Dodge Ram Lighting and Electrical Problems

edited May 2018 in Dodge
2000 Dodge Ram 1500 pickup. When tryed to put on high beams headlights would go out, after a couple of attempts they would come back on. Replaced high beam switch on column and now the high beam indicator light on the dash stays on all of the time and the low beams appear to be very dim.


  • have recently experienced the lights in my truck periodically dimming and then returning back to normal. This happens with or with out the head lights being on, while driving in traffic or waiting at a stop light, At times it seems like the engine revs up a little but not all the time. I have performed a number of searches on the web trying to find additional informaiton on this. I have been told by the dealer service department that this is normal, but others who own Dodge 2500's do not seem to have this problem, does anyone have any suggestions?
  • Cummins diesel or gas rig?

    I have a 2003 Dodge, diesel, 2500 quad cab 2wd. I am also having problems with the cab lights dimming and returning to normal with circumstances equivalent. Thank You in advance for any advice or direction.

    I have a 2003 2500 CTD quad cab long bed 4x4
    I get a violent bouncing from side to side once in a while usualy on the freeway at higher speeds the only way to stop the bouncing is to pull over and stop. It only doses this from time to time and there is no set patern .the stering wheel dont shake or pull the truck continues straight but whole truck bounces very hard from side to side almost as if wheels are coming off the ground, The dealer can not find any thing wrong. any suggestions on a way to stop this bouncing?
  • For some strange reason, my headlights (low beams) speradically come on for no reason while the truck is turned off. The weired thing is that if you disconnect all of the fuses, the lights still stay on. The only way to turn them off is by disconnecting the battery. Can anyone give me some direction on where to start investigating this issue?

    Hi Christine, and welcome to Edmunds!

    In my pre-delivery inspection of my 96 3500, I noticed the brake lights stayed on... not good for a brand new truck just off the carrier. Dealer service department took care of it before delivery. Usually it's a fuse/relay issue, but in your case, I'd say there are two additional things to look at...

    - for the headlights, you likely got something wet while off-roading. You probably want to check the power module and see if there's water in it - and get it dried.

    - for your reverse lights, you likely have a wriring issue between the trans and the light connection. There's a solenoid that is triggered when the shifter is properly engaged in reverse that activates the reverse lights - that would be my first suggestion.

    And as mentioned in the post box, please, do not include your email address in your posts. We can't protect you from spammers or other malicious use that way. just make your email "public" in your profile (use the Prefertences" link in the left margin), and only logged i members will have access to it.

    Thanks alot for the information! I will pass the information on to my friendly neighborhood mechanic!
    As for my e-mail address (oops) I will see about removing that information.

    Thanks again, Christina

    I noticed that I have NO brake lights. I keep blowing the fuse and can't figure out why. I changed the stop light switch under the dash, checked all the light housings and still keep blowing the fuse, anybody have any suggestions, I could use the help...Thanks Bill

    i had the same issue with my ford pickup
    apparently there is something frozen in suspension I took it to a leafspring shop for 800.00 they fixed it my truck the steering shook also
  • I have the same problem with my truck. Occasionaly my parking lights come on or my fog lights come on automatically. They are turned off inside the truck, but I don't know what is causing the problem. I have only owned the truck for about a month, but as far as I know, it has not been offroading.

    Did you find out what was happening with your truck?

    Please let me know.

  • I have a 2001 Dodge Ram, 4x4, Tow Package, the works, but I can't get the tow lights to work. If anyone knows which fuse this is or just any tips then please respond. P.S.- I have connected everything correctly and the trailer lights do work on another vehicle. Thank You
  • My 2004 Dodge Ram 1500st engine light stays on is there any way to reset it
  • problem with dash guages not working. odometer blinks three times than says no bus. tapped on dash cover and blew fuse for dash lights. guages has come back on one time but went off again. has been happening for about two weeks. any help?
  • KCRamKCRam Mt. Arlington NJPosts: 3,516
    NO BUS means the dash has lost communication with the computers. Could just be a connection, could be more serious (fried wires).

  • The overdrive light and switch on the dash...what is it telling me? Is it in O/D when the light is OFF? I can't tell the difference, at high speed of course.
  • KCRamKCRam Mt. Arlington NJPosts: 3,516
    Is it in O/D when the light is OFF?

    That is correct :)

  • Thanks! :) I thought so but wanted to be sure before I investigated further whether or not the O/D was working.
  • I am currently having the same problem with my 98 Ram 1500. Have you solved your problem yet? I'm tempted to pull the instrument cluster and grease the terminal contacts as suggested in a previous post on the same problem.

    My husband just went thru weeks of the same problem. His truck just wouldn't start. So he replaced the time & control mod. and that didn't work. Then when he tried starting it, it would blink 3 times and say "no bus". So he replaced the crank sensor, still didn't work. He tried numorous other things (like checking conections & fueses) and nothing worked. Tried calling a local dealer to confirm that the time and control mod. DIDN'T have to be programed for he truck.....3 times they said NO. We finally had it towed in to be put on a computer. GUESS WHAT!!! That mod. DOES have to be have an anti-theft system. Hope this helps someone!!

    I have a 2006 Dodge Ram 2500 TRX4 with the 5.9L CTD. About 3 weeks ago I started the truck in the morning like always and I noticed that the lights dimmed and then got bright again and then dimmed and so on and so forth for about 3 minutes, and as I watch my volts meter it is cycling in sequence with the lights. It has been getting progressively worse to the point that if it sits for more than 3 hours it will cycle. I have also noticed that it affects the RPM if higher than 1000RPM. If anyone has an idea of what is going on please let me know.

    Completely normal and described in your owner's manual. Now that it's cold, the grid heater (which warms the intake air before it reaches the cylinder) will cycle for three minutes after the engine is started to allow better combustion and less smoke. You'll experience this all winter, nothing to worry about.

  • I recently purchased a 2001 4x4 Quad from a private party and within 24 hours check engine lite came on. Took to dealer and it turned out that heads had multiple cracks. (Came to find out through a little research that this is a common issue on 5.9L after 100,000 mi. Bad design on valve wall thickness, fixed in newer heads). Anyways on way to get this fixed a few weeks later I started truck and all dash went dead and "No Buss" came up. First response from Dodge Dlr. was that it was either a minor short in Power Control Module(PCM) or it was failed all together. Heading to Mech.for head replacement I stopped at carwash to wash off mud in engine compartment, when I got back in truck all dash back to normal, YEA!, apparently just a short and saved $800.00 While at independant mechanic to get new heads I noticed small knock in low end as well. Mech. heard as well and decided to replace engine with factory remanufactured long block. Upon completion new engine would not fire. Indie Mechanic had to send to Dodge Dlr so a new "AirBag Module" could be installed and computer re-programmed. $460.00 for module and $300.00 for labor, Hmm there goes the aforementioned $800 bucks. Hope this helps someone out there. Truck runs great now. Scott

    I have the same problem on my 2006 3500 with 6400 miles. I find it hard to believe this is normal with sensitive computers and electrical components. Would this not be a voltage spike with heater making headlights go dim and back to normal brightness? Please e-mail me...strength in numbers!
  • My 06 3500 CTD Mega does it too. Normal, normal, normal...and in the owner's manual. Just enjoy!
