    Hi, the rear a/c blower motor does not work when the switch is turned on any of the speed settings. I checked the switch with a meter and checked all the fuses. The front air and blower motor work fine. Any help ? Thanks. Would you know where the rear blower motor is located so I may check that also?

    Just an update...Took my truck to the dealer.. They said they could not duplicate customer complaint..I get that a lot at dealers..They drove it for a total of 1 mile..They said speedometer was fine.. While I was having my air conditioning recharged, I noticed 4 wires coming out of the fuse and relay box in engine compartment were broken and 1 was barely made, together by just a strand.. I figured this may be a problem..Repaired the wires and all is now working fine...So much for the 5 star Dodge dealer... I even told them I thought it was a wiring harness or connecter.. By the way this is Cortese Dodge in Rochester, NY...Thought you guys might want to know...

    I have had the Lamp Out Light on for the last couple of weeks. I've replaced fuses and a couple of burnt out bulbs. But I still have it on.

    Last time I took it to a dealership I was charged $600 for them to replace a cab light. I think I have an electrical issue because I've noticed that when I hit a patch of rough road, my stereo system dies and that light comes on intermittently. Is there something I can do about that?

    I am in need of a power distrabution center for my 1995 Dodge Ram 2500 Turbo Diesel I have exhausted my resources.

    Where is the closest Place I can tap into the Speed Signal Input Wire on my Dodge Ram 1500 qc?

    I am installing a Pioneer AVIC-Z2 and and this is the only wire I don't know where to connect, everything else is connected (except battery and harness clip) And in case you were wondering how a double DIN fit in a DIN 1/2 opening,...I also modified dash so it would fit.

    Thanks in advance

    Bill, I am also having problems with my brake lights, keep blowing one on the left rear. But this is also causing other problems, when I replace the light i start getting an
    alarm everytime i press on the brake pedal, then the other day it switched from the brake pedal to every time i pressed
    on the accelarator. Finally the blub blew again so now I'm just going to let the "Lamp out " light and let the alarm
    go off for the few seconds. I hate to take it to the dealer and they will cost an arm and a leg to try and trace it out. Did you find out what your problem was yet>>

    I replaced battery 4 days ago thinking that would resolve the prob. It only takes about 1 hour and the battery is totally dead I had the alternator checked and they said it was ok and charging good. Its was checked on a Load tester. SO now when I go anywhere I disconect my batt cable if I need to stay longer than 5 min.

    The 20 amp fuse in the stop light circuit keeps blowing. I can replace the fuse and the stop lights will work but at some stage in a short drive the fuse blows. With the truck stationary it seems OK. I have tested continuity on the circuits from power source to multi function switch and discovered no problems. I have checked to high level stop light and all appears OK. I have replaced the stop light switch with a new one but the problem still persists. I have run out of ideas so please, what do I do/check next? The wiring schematics show that from the multi function switch to the rear lamp units the brake lights circuit shares the turn signal circuits. The turn signals are not affected and work normally throughout.

    Since you have a 2500 Cummins, I'm going to make a safe assumption you also have the towing package. Check the brake light wiring for the trailer hookup - that can affect your main circuit in the manner you're experiencing.

  • Thanks for the tip and you are correct, I do have the factory fitted tow package. I will check it out tomorrow and let you know the result.
  • Nice try but no prize!!! The tow package checks out as far as I am able to tell. This problem is obviously a dead short caused by movement of the truck. I replaced the fuse after checking the tow package circuits and drove to the end of the driveway (200 yards). The fuse had blown!! Maybe it's time to sell the truck??? Only joking but now I'm totally out of ideas.

    Wow... definitely a bad short somewhere in the circuit... something tells me that will take an electrical specialist to trace it.

    I think you're going to have to get under the truck and inspect the full length of the wiring harness looking for a spot where a wire is contacting ground (frame or sheet metal).

  • My instrument cluster has been shutting off and displaying a NO BUS message meaning it is not communicating with the rest of the vehicle controllers. This problem used to go away with a swift thud to the dash panel. However, the problem is getting progressively worse and is becoming harder to correct with my fist.

    Since the instrument cluster goes on/off with a impact, I believe the problem is the cluster itself. Any suggestions...?
  • dustykdustyk Posts: 2,926
    The message means the cluster is not communicating with the PCM.

    Check for poor connections to the instrument cluster. If the connections are good the cluster is a prime suspect.

  • I just had the same problem. Every thing works but the dash. I have seen several thins mentioned here but a solution. Anyone know for sure. I also checked my batt just with a meter and it shows 12.15. Could it possibly be a bad batt.
  • dustykdustyk Posts: 2,926
    The 12.15 volts at the terminals sounds a low for a fresh battery, but not for one that's got some time on it. Also, be aware that there is approximately 15-75 miiliamps being drawn by the onboard computers. The most accurate method would be to remove the IOD fuse and/or disconnect the battery cable from the battery before measuring.

    Best regards,
    Dusty
  • Hi,
    I'm having a problem with no tail lights or parking lights on my 2004 Dodge Ram 1500 4x4 5.7l Brake lights and headlights seem to fine, all fuses and relays are good, seems to have lost a ground to the relay, if anyone can give me some advice it would be much helpful
    Thanks
  • I have a similair problem with my 00 dakota. After pulling a trailer with bad wires I had a problem arise. I now have no tail lights and no instrument panel lights. I have check all fuses, I even went ahead and replaced the headlight switch box and still nothing. Any ideas ?? anyone?
  • I have figured it out on my own.
    After removing my hookup for my 7 pole trailer plug, retraced the lights and re-installing the light switch. I then re-re-re and yes re checked the fuse I finallaly found a blown fuse for the PARK LP 15amp. Ya how stupid do i feel know! Now I will have to try a new hook up for my trailer plug and Re wire my entire trailer wiring!
    Yah
  • I'm having the exact same problem on my 2002 Dodge Ram 1500. Did you find a fix for this problem?
  • I have a '06 Ram 3500 with most of the bells & whistles, including adjustable pedals. Lately, my brake lights have been staying on after I park the truck, until I lift up the brake pedal to shut them off. This is obviously a PITA, and one of these days, I am going to forget and melt the sockets from bulb heat issues. I had a look, but can't see an obvious way to adjust the switch stroke or pedal spring tension. Should I just replace the switch? Or, does anyone here have any experience with the same issue on this series of truck?
  • I have a lamp out message on my dash. Neither of my rear brake lights work, however the single, upper brake light near the roof on the back of the cab does work.

    I have checked all the fuses and bulbs--they are good.

    Any ideas?

    if you have a trailer light hook up drop your spare and check you wires. i had the same problem with mine and i had to replace my break light switch to.

    take a crecent wrench and bend the tab that holds you stop light switch until it goes out
