My truck is a '97 K1500 x-cab. I have water coming in the truck from somewhere when it rains. It's not a flood, but enough to be of concern. It ends up coming out in the area of the blower motor/vent assembly under the dash on the passenger side and landing on the floor. It's NOT coolant. Only thing I can figure is there's a leak in the body somewhere or a drain hole that I plugged up from my days in the mud. Any suggestions would be greatly appreciated. I'm figuring on running water down the through the cowl and watching to see if I can see it come in the cab somewhere.
Thanks! Matt

My 94 and my dad's 96 burb both have that too. It is just a couple drops in heavy rain only so we don't worry about it. If there is a cheap, easy fix would be interested though.

That happened to me once. I think its from splanshing thru puddles. I went thru one at like 50mph and the next day there was water. I dont go thru puddle fast anymore
