Hi,
 
 My 2002 ext cab (when New) had a similar issue on the passenger's side.
 
At top passemger's corner of the windshield - the roof is welded to the upright suport from the lower body. Outside it looked Ok - but under the windshield rubber trim strip - at the top corner - it was open a tad between the metal supports. Water was getting down around the windshield rubber outside cosmetic rubber trim would run down under this rubber trim - and instead of running down around the windshield glass/ seal - it went inside the support weld hole and was dripping inside and down the inside of the support into the passember kickpanel area - and leaking into the passemger floor.
 
The dealer finally pull away the inside corner of the head liner - say the issue, caulked it up - and I had no more issues....
 
Hope this helps ...

Thanks! That will be another area to check once winter is over.

Did you pull up the carpet to see this? Or were you some how able to see the leak from the engine side?
Thanks!

I had the same problem with my 1993 S-10 pickup. I thought it was leaking through the windshield when it rained but it still did after sealing the whole thing up. So, I unscrewed and took off the plastic panels off the body(on the driver's side, left of the pedals)and there is a big hole in the metal body with a black patch on it that was coming off. I poured water on the corner of the windshield and yep that's where it was leaking in. Not sure why there is a hole there (maybe to lighten the truck?) and if it's in your S-10. I just know it was a pain in the rear figuring out the whole mess and I just patched it up with another patch and some adhesive. Problem solved.

Thanks. That sounds like it might be it for me as well. We checked a couple other "common" sources for the same issue with no luck so hopefully when I get the carpet up this summer I will find it.
Thanks Again!!

i have this same problem with a 2000 gmc sonoma. i found that mine had been leaking where someone installed a sun deflector and tried to put the seal back on with blue goo, after a while the silicone got weathered and it started leaking.

in the fire wall a windshield drain or slanted channel running from the passenger side of the cab to the drivers side,was created to get rid of water from the windshield (just under the cowling). tthe problem is usually due to a drain hole getting stopped up by leaves or other debris and letting the water sit and corrode through to the inside of te cab. remove the fender and use body sealer or even liquid nails to fill it in, this corrosion can also be caused by a build up of the sealant that gm uses on its pannels and "dams up" the water.

My 97 S-10 had wet carpet on the driver side. Turned out to be two things. #1. The back glass was leaking at the driver side top corner. Looked like the headliner got stuck in the glass adhesive when assembled.
#2 The body seam on the driver side of the back of the cab wasn't caulked properly at the factory. Bead of sealer was an inch away frm the seam. Besides it being a quality disaster, I enjoyed driving it.
