The driver side floor of my truck always had an inch of water whenever it rained.

I sealed the vent hole behind the left kick panel, but there is still water leaking in. I sprayed the wind shield with garden hose, but didn't notice any leaks.

I'm thinking about taking the truck to a car wash, and see if I can spot the problem. Would you guys be able to give me some suggestions on where it might leak?

(My truck is a 1992 S-10 Chevy with a 4.3 engine.)

Thank you!

 

Check the cowl drains. They are located on either side of the cowl, near the fenders.
