  • out what was wrong, dh got tired of me and the kids getting stranded and he bought me a newer van. There might be water in an area where the computer is that is shorting out the BCM. Has your mechanic run diagnostic codes? Ours did and this is what he found after four hours on the computer trying to find out what that code meant. I think it was 1788 or 1728. It worked for us a few days, then back to the same problem, but we had not done what you just replaced. We just weren't willing to keep spending money on repairs. It's our only transportation. Hope that helps!
  • Hello!
    I solved the computer reset problem according to your prodedure, but I got another serious problem: The radiator fan was still running when I turned off the engine. After the radiator fan stopped running 20-30 min later I tried to start engine again and failed to start it (it was dead again) and the dash panel are dark. Could it be radiator fan relay problem? I met with this kind of problem about two years ago and the mechanic replaced the radiator fan relay. But I hate to go to auto repair shop (it will cost a lot of labor fee) and want to replace it myself.(If it is this problem with replay). Any suggestion will be appreciated. Thanks in advance!

    This problem started a month ago and I have no idea how to fix it!
    When I turn the key off the running lights stay on,the high beam indicator light on the dash stays lit!
    Up till now I have been unplugging the head lights at the lights under the hood to save the battery!
    The head lights work fine high and low beam but the high beam indicator is always on.
    Any help would be much appreciated. :(

    I'll look in a repair manual I have a little later and see if has any information on the fan relay. I'll let you know what I find out. ;-)

    Best Regards,

    I have a 91 Grand Caravan that was doing the same thing ,my mechanic replaced sensors computer and more to no avail.
    Some one suggested testing the fuel pressure,after doing that it was decided it was the fuel pump.
    Made sense as we had replaced the gas tank and it was after that it started to act up, to make a long story a little shorter after trying two used pumps and not fixing the problem I installed a new pump and have not had a problem since ( 14 Months ) .

    I have a 2001 Dodge Grand Caravan and when it is turned off and unattended the parking lights and tail lights come on by them self. Some time they flash. Also when driving the car some times the lights just go off and come back on. Any ideas.
  • I got a 2002 Lxi. Recently it has been acting wierd. When I open the driver or passenger door the parking, rear and fog lights go on. They never did that before. It does not have auto lights either. Now when I open the door and they go on, if I turn the light switch to parking lights then the fog lights go off but parking light are still on. If I then pull out the switch for the fog lights then all the lights go off just like the switch is set to off. If I turn the switch to full lights then they work fine and if I pull out the fog lamps they turn on. It is just like the Off and parking light/pull out fog setting is mixed up. Anyone heard of this problem and any suggestions what to do? I thought of disconnecting the battery and see if that will reset it. thanks

    Answered Question


    Subject Plymouth Voyager Car Alarm
    Question 98 Voyager, bought used, power locks, no remotes, alarm arms when doors lock. Car alarm has started going off in the middle of the night, other times, etc. for no reason. Is there a way I can disable the alarm?

    ---------------------------------------------------------------------------------

    Answer At least we know it's installed correctly
    which is actually a good thing here.

    Ok, try this.
    Put the key in the ignition, and turn forward
    all the way just before cranking. Then within
    5 seconds, locate, press and hold in the
    valet/overide button, found under the
    dash area, (push button, spring loaded)
    until the installed LED (the blinking light)
    in your dash area goes on solid,
    and the siren chirps once.

    (Your valet switch might be the toggle
    (on/off) type. in this case, key on,
    flip switch in opposite direction,
    then turn the key off.)

    This should reset the alarm, and reset
    the grounded relay on the starter wire,
    allowing you to start the engine.

    At this point, the only thing working would
    be the keyless entry from the alarm,
    if it came equipped that way.

    Just Repeat these steps to place it
    back to usable armed mode.
    You may get 2 chirps, confirming it,
    and the lights may flash twice as well.

    That should do it.
    If you want to remove it at this point,
    take it to your neighborhood installer
    for this, or buy the wiring chart
    (Go to: www.vehiclewires.com)
    for the vehicle, and reverse engineer it wire
    by wire, until safely removed.

    If it does not work out this way,
    you will have to replace the system
    with one you know how to operate
    and what to expect. Don't want to
    get stuck in another bad situation.

    I hope this helped..

    Not sure if you got your answer yet, but I have been experiencing the same problem on our 1998 GC. Happened today during a snow-fall; I had to drive home with no heat, no wipers, no windows! Just figured out what was going on. Somewhere (either in this string or another user group thread on this issue) there was a reccomendation to check the key rotation in the ignition. So, I went out and tried it. I found that our ignition is is warn enough that the key will stay too far forward (not enough to keep the starter running contniously) - far enough to kill the wipers, blower, etc. I guess these must be shut off during an ignition crank, such to provide enough amperage to the starter. Anyways, I found that if I rotated the key back just slightly (not far enough to turn the engine off), I could get all the accessories working again. Try it. You can find the "sweet spot" without even starting the car. If you rotate the key in the ignition to just before the point where the starter kicks in, you can move the key back and forth and find the point where the electronics work/don't work (try it with the blower on so you know its working.
  • I have a 99 Dodge GRand Caravan, I don't know what an LXI is, but the left blinker would sometimes not work. Then the headlights would stay on after the car was turned off. So my husband took it apart and the lights wouldn't come on at all when it was started. He was going to bypass it and just give me a seperate switch for the blinker and lights. Then the interior lights wouldn't turn off and the engine wouldn't stay running. So he said take it to the dealer. I hope to find out today what is wrong and will let you know. :confuse:

    Thank you very, very, very, much. I followed your instructions and the flashing wiper problems were fixed to a "T".
    The only lights that are still flashing are the ac button and the recirculating button. I have a 1998 Dodge Caravan.Do you have any instructions on how to turn off those blinking lights.
  • 94Dodge Grand Caravan, 230K miles, 3.8 engine. One night I got home and noticed my brake lights were stuck on after shutting everything off. It being late and dark, I decided to pull the fuse and fix it tomorrow. While doing that I shorted something on the fuse panel with my pliers, causing a spark. Next day, I smelled burnt insulation. i checked all fuses and they were OK. Even the brakes were working properly when I put the fuse back in(it was OK).

    Several things did not work, however: Remote control, electric locks, radio, ceiling lights, and the ammeter guage(Other guages OK).

    The owner's manual speaks of a circuit breaker behind the center column. Could that be the culpret? If so, exactly where is it and what kind of circuit breaker is it.

    I checked all the wires I could see, and no burnt places.
  • Did anyone find an answer to the question. My 98 caravan is doing the some thing.
  • When I turn on my van right running light comes on, turn on headlights and the right light stays on, switch to bright lights and the right one turns off and the left one comes on. when they are on bright and you pull and hold dimmer switch both are on. I have replaced both headlights and the dimmer switch. Please help!!!!!!!!
  • Hello Aprendiz,

    Just went through this myself. There is a fuse box inside the hood towards the drivers side. I'm not looking at it now but the fuses are well diagramed on the underside of the fuse box cover. It's a 20 amp fuse.

    1997 Plymouth Voyager. When we moderately corner to the right, the interior lights flash, door locks cycle locked/unlocked repeatedly, and door ajar light flashes on/off. Once it starts, it continues randomly for up to several minutes. Additionally, an older problem has been the wipers. They turn on for no reason, and continue wiping until the wipers are cycled on and then off again. The wiper problem is rare, occurring only about twice a month, but the lights/locks have been continuous for a couple of weeks now. Any help here, as my wife rightfully won't drive at night now, as this presents quite a driver distraction.
  • Have Canadian 2006 GC with daytime running lights. When I put on 4way flashers the headlights go out. When I turn the flashers off the lights come back on. Also each light will go out if that side turn signal is activated - and will come back on when signal's canceled.
    Any suggestions as to where I look for the problem ???

    This is a post I located on a Google group. The part referred to is apparently #4685433, lists about $109, and is a 4-way sensor that incorporates door ajar, locks, windows, and interior lights. Haven't verified that though or found the part available for order anywhere.

    Quoted:
    There is an updated door ajar switch for the sliding door, Assuming that the door is adjusted properly , the new switch should take care of your problem

    My 1998 Grand voyager had the exact same problem - took it to the dealer (my independent mechanic couldn't fix because it involves chrysler software progamming). Dealer knew exactly what the prblem was right away - one of the computer modules is bad and has to be replaced. New mocule has to be programmed after installation by a dealer only. Cost is about $700 - in New hampshire anyway. My son has the car at collge, the repair slip is in the glove box - or I'd give you more exact detail. Hope this helps.
