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!
