Hi, my 98 C2500,5.7 Vortec extended cab has a water leak into the heater blower motor. when the truck sits and it rains, water finds it's way into the blower housing. Anyone have any idea where this might be coming from??

Thanks

Sure it's not anti-freeze? Does it have a "sweet" smell? Sounds like a leaky heater core to me. Check your radiator fluid level.

if leaf debris has clogged the drain holes in your fresh air intake, it will run in that area of the cab.

Remove the wiper arms and then the cowl panel, you will most likely find crud in there causing water to go in to the box.
