1999 plymouth grand voyager voltage regulator

I own a 1999 plymouth grand voyager 3.8L engine. When the problem initially started, everything electronic died off one by one (radio, headlights) I had someone jump me and the van went about another 10 feet before dying again. I put on my hazard lights and they were going in and out but when they were on, all of my inside lights were also blinking with the hazards. At that point I believed it to be either the alternator or the battery, I replaced the battery first...ran until the battery ran out of juice, took the alternator out and had it checked at autozone, the alternator is running where it should be. I am now lost on where to look next, I was thinking the voltage regulator but I am not positive and I am not sure where to find it either

If your alternator is good and your connections are good (alt and battery) then sadly the voltage regulator is not letting it charge your battery, the regulator on this vehicle is part of the ecm and is not seviced seprately Hate to give you bad news because the ecm is not very cheap. Hope this helps Bill

Not all bench tests on alternators are reliable. That battery has to be brought back to a full charge. It could be a simple connection to the alternator. Check those battery cables as well make sure the ground wire is secure.

    voltage regulator is in the cpu , unit.... if your looking to change this out , i'd find a local salvage yard.... be the cheapest , if you look out in the yards and find one that has been crashed , is your best bet to find a good one....... and not cost a ton of money... check with local parts house as to the price of a new one , just so your not getting ripped off at the salvage yards ...

SOURCE: 1992 plymouth grand voyager wont stay running

i can tell you its not the fuel pump.if you smell fuel then the pump is working right,you may have a weak crankshaft sensor though which would keep it from starting and running. but its definately not the fuel pump maybe you have water in your gas

SOURCE: 1996 Plymouth Voyager missing violently, hesitating, dying,

Take it over to a Auto Zone store they advertize that they will read the diagnostic cods for free. with the check engine light on there are codes logged in the cpu. the codes will point you in the direction to go. this will save you lots of time.

SOURCE: where is the voltage regulator on a 1999 plymouth

Just to make it clear...I didn't say that the regulator was drawing power, ranthe that if the alternator checked out, the regulator may not be allowing it to charge properly.

SOURCE: Alarm is going off and the Plymouth Grand Voyager won't start.

Try using your key (after reconnecting battery) on the drivers door, to lock, and unlock it. There are so many different vehicles with different methods, you may have to call dealer service dept, with your VIN # and name, and they should be able to give correct procedure to disarm security system. Check owners manual as well.

1999 Plymouth grand voyager engine hood will not open after operating the release lever inside car. Eventually it loosens and open days after operating the lever. Any thoughts on how to repair? Thanks Ed

I had this problem on mine i loosend up the cable end by the hood latch and checked to make sure nothing was bent, you can also buy a new cable for it as it may be broken somewhere in the way for around $25. but check the end at the hood latch usually gets gummed up with grease and dirt

Until you fix the problem, you should remove the fuse. The battery will run down !!

This problem is most likely caused by the BCM (Body Control Module). The BCM is located inside. It is behind the fuses and has lots of connections. After you remove the BCM note of the Part Number P/N. The replacement BCM must have the same part number. From all my research you can get a new one for from $800 to $1500 or get one from a salvage yard for $10 -$50.
Write down the odometer readings before you change this unit. The replacement unit may have a different mileage showing.
When you install the BCM make sure everything works. Try doors, windows, air, fan, remote, turn signals, hazard, lights, backup lights, horn, brakes, dash lights, etc, etc. This unit controls a number of functions and will have to "learn" your vehicle.
And yes, it's a good idea to disconnect the battery ground cable before replacing the unit.
