ECM not communicating with alternator's voltage regulator.
Battery is not charging. Was told regulater bad. Replaced alternator have same problem. Suspected bad wire to ECM or ECM.

The minivan never claimed to be anything but a family hauler, falling somewhere between a truck and a station wagon. Handling like a car, loaded with interior creature comforts, but with lots of cargo room, the 1998 Dodge Grand Caravan has earned many faithful owners and many grateful moms.
In addition to the 3.0-liter, 141-hp V6 or a 3.3-liter, 158-hp V6 engine, the 3.8-liter V6 raised its horsepower to 180 (from 162) in the 1998 Grand Caravan. Base model Grand Caravans housed the 3.0 V6, while all others came standard with the 3.3 V6. AWD Grand Caravans were equipped with the 3.8 V6. On SE models, a Sport Package with enhanced suspension gives the minivan a more energetic feel on the road, though it is not available with the 3.8 V6.
What's the number one function of a minivan? Of course it's hauling groceries, and new in the 1998 Grand Caravan are hooks on the backs of the rear seats to hold groceries more securely. For extra storage, the rear seats can be fairly easily rolled out for removal.
Battery is not charging. Was told regulater bad. Replaced alternator have same problem. Suspected bad wire to ECM or ECM.
I have a 1998 Dodge caravan. The drivers side rear turn signal and hazard do not work. I know the bulb is good because the tailights work. I replaced the bulb anyway and it made no difference. The signal indicator on the instrument panel blinks fast and so does the front blinker. I can't seem to find information that explains why just one light would malfunction.just one side.
What is the towing capacity of the Grand Caravan? It has the 3.8L engine and heavy duty suspension. Thanks
hey guys i was driving my van fine next time i got in. it started and immediatly died and after that it cranks but wont start i dont hear the fuel pump maybe the issue is there were do i start in diagnoseing
I changed my brakes all the way around. I have front disc and rear drum brakes. I Bled them starting from the furthest away from the master cylinder and worked my way to the front . They worked Good. After a week it seem like they needed bled again. I checked the fluiid and added some. My brakes don't work until I press halfway down on the brake petal, if I go alittle further and to the floor it seems like they stop working until I lift up and press again but still only works when petal is pressed halfway down and barely slows you down when to the floor. I noticed my ABS light was on so I looked around some. I found that my rear passenger side abs wheel speed sensor was missing it's bolt and was just hanging there out of it's correct place. Could this be causing air to get into my braking system?
