    All of the post shutdown power usage is controlled by the solid state computers.

    I would say you should hook an ammeter to the car and see what stops the power usage with pulling the fuses. You will want to wait awhile after you connect the meter before seeing what is using power, just to let the computers reset.
    Candy the van. '98 Sport 3.8L 132,200 miles. Used trans at ~96k. Great piece of my life and a fine van.

    Shipo a van with all the gadgets or a base van shouldn't matter, as all the gadgets should be turned off within 30 seconds with the key in the off position. Even if you have the swich turned to accessory everything except for the radio should quit after 30 seconds. I don't think the window will roll down with the key on accessory... but they may... I ran a 9" TV/VCR for an hour before on only the battery playing a video tape. I had the jumper cables out ready to boost it, but it started right up.

    Something is pulling current. It may be something that has to go to the dealer and be connected to the DRB III to find out what is still on. Could be the circuit for the heated seats or radio or... well anything.

    One thing you could do, pull the IOD fuse and see if it does it then. It shouldn't. If it does, something that connects directly to battery power is drawing current, like the starter circuit.

    Just one more thought, what CCA battery are you using? It really should be over 550. I always put a 850 on mine when the battery dies.

    For at least the Gen 3 and Gen 4 vans, the Power Windows will indeed go up and down when the key is in the accessory postion.

    Yeah, if you look over the the "For Sale" section you'll see the thread.

    Long story short, flybyy is selling his black (rust free) FWD 1998 T&C LXi with something shy of 180,000 miles, and my (soon to be 16 year old) son just got a job as a snowboard instructor and he'll be needing a ride that can schlepp several kids and a bunch of snowboard equipment up to the slopes. The confluence of events worked out perfectly.

    I haven't had a chance to look at my route yet, and if I-95 looks to be the route, I'd gladly meet you for a bite to eat.

    I couldn't remember... seemed like I thought they did... but didn't think they did... anyway try the IOD fuse trick. That will point you in the right direction.

    I've learned this lesson the hardway myself and put nothing but 850 CCA batteries in both the 1996 and 2000 3.3/3.8.

    Shipo....The problems you describe are the same we had in our 2004 Pacifica and now 2005 T&C. Chrysler from the get go puts inadequate batteries in these cars. We had to jump the Pacifica a few times and what I found out the wife was doing was leaving the key in the "on" position, leaving the door open, auto climate blowing the fans and all the darn interior lights were on. It would kill the battery in a heart beat. It took 2 times for her to realize to turn the lights off, use accessory and make sure the hvac system was off. This helped in the pacifica but we never changed the battery in 4 years.

    We traded to the 2005 T&C and the wife new what to do this time if she was sitting in the car for extended periods. Doing this correctly, the battery would only last 15 minutes or so. The battery had already been upgraded to an interstate by the previous owner and was only 2.5 years old. I thought we had a draw problem as well but when I checked the current draw at rest, it was very low. Simply putting in a new battery from Costco.. 800+ CCA solved our problems. We also don't use the auto headlight delay after van is shutoff feature any more either. I am not saying a new battery will solve your problem, I am just checking how you use the system. If we know we will leave a door open for a long loading period.. we turn the interior lights off before the auto off does it after 15 minutes or so.

    It seems these cars with all the fancy electronics are real hard on batteries these days. Do a current test with the car at rest and get back to us.

    Given my travel plans for the week, I won't be able to look at it until this Sunday at the earliest, probably the weekend after.
