    Hi there. I've got a 2002 Express 1500 conversion van.
    When I shut my engine off, the blower motor is still getting power. Even turning off the main selector switch I still end up with a dead battery the next morning.

    After hours of scouring the internet on a solution, it seem's changing the blower motor resister was said to fix it.

    No dice. put in a new resistor & no difference.

    Does anyone have an idea what the problem might be?

    Thank's for any help you guy's can offer.

    I'm guessing this issue must be pretty rare.:grrrrrr:

    i would pull the hvac unit out and see if possibly something is melted. maybe a short happend and jumped somehting causing constant power. if all fails. you can always un hook power wire and wire in a toggle switch to manually kick the blower on and off. be sure to use an inline fuse.

    Yeah, as soon as it warms up a bit here, I'll start probing the wiring harness. Tried a few days ago, but the wires & plastic sheathing are so cold they won't bend & I'm worried about breaking something from the cold brittleness.

    Just a guess here, but maybe an ignition switch?

    Well diagnosing this problem is gonna be a bit harder now. About a week ago it went away. I have an idea what it is, but won't know for sure until I unwrap the wire loom. Have to fix it permanently because sure as **** it'll come back to bite me at the worst possible time :rules:

    Switch has always worked fine, both ignition & master fan control. There's got to be a bad wire or connection somewhere. I'm thinking it's a wire or 2 that has the plastic sheath abraded. I should know in a few days, finally supposed to be warm enough to work on it outside. Conversion top makes it too high to fit in the garage.:grrrrrr:
