Default Water leak on drivers floorboard

On my '93, I've been getting water on the drivers side floor board. Just the middle of the floor is wet. about a 12 x 12 area. I can't see any leakage coming from the door seal or down the firewall. Could water be coming from the heater vents because the cowl drain tubes are blocked? BTW I don't have a sunroof.

If the heater vents were draining in the car it would more likely be the passenger side. I would look for a rust hole. Pull up the carpet and I'm sure you will find the problem.

Thanks for the advice! I'll pull the carpet and see what I find.

My 96 Bonneville had about 7 leaks from under the windshield.

Well, I pulled the carpet back and had my wife hose down the car while I was inside. I found water leaking down from the upper corner of the door seal. It was running along the pinch weld and then down dehind the kick panel. I really hate the door seals these cars have. It seems that GM did a poor job at the corners fit. Are replacemants available in the aftermarket?

John;

The seals are dealer parts. You may be able to pick up a decent gently used one from a junk yard.

It'* not that they were installed in a ****-poor fashion, its because over time, the seals shrink and create gaps in the corners. Same thing happened to mine.
