Hey all, my 1995 Chevy K1500 has leaking water into the passenger floorboard. Can’t find anywhere it could be leaking from. It hasn’t rained and the floorboard does not smell like antifreeze. Any info or suggestions would be greatly appreciated, thanks.

We have the same thing on our 1995 Sub.
My son said he found on a forum where some said it was coming from the cowl area.
I am not entirely sure where, but rain water leaks in...

Heater core. Mine was dripping out of the bottom of the cab. I had to loop the heater hoses... for now... Its warm enough, no heater necessary for another 6 months. The carpet is dry but kind of oily now.

If you've used the a/c or defrost I would check the drain tube for sure. Possibly modify. I've seen some cases where just the right wind will cause the water to shoot right back up into the hose or find a way through the firewall.

If not, with no rain, its the heater core.

I should’ve mentioned the truck has the A/C option, but it is currently not working. I’ve checked the condensation drain and the liquid is not sticky.

Mine is only when it rains. Nothing obvious in the cowl area but i still need to test to make sure its draining
