clogged drainage hole in the cowl (under the wipers)...
Mine does too, I've not gotten around to making an attempt to fix it just yet, however, there is like a rubber strip on the bottom of the windshield that I think is supposed to keep the water out, well I noticed that on my Beretta, it was slightly coming off in some places, enough that I can put one to two fingers in the gap. I'm not sure what to use to seal it though.
On the front left of the engine.
You cannot repair the water pump. It needs to be replaced.
sounds like ya have a heater core leak . time to take her apart
Are you running the air conditioner? If the drain line is plugged, it will leak water (condensation) onto the passenger side floor.
You have the infamous "Wet Carpet Syndrome". Check your cowl for leaks.
The seal is shot, time to replace the water pump. Do not let engine over heat!
My 95 blazer has a leak that normally shows up after a heavy rain. It is caused by water running down the windshield into the air duct outside the vehicle. The water runs down the passenger side of the duct where the fresh air vent is located. If the fresh air vent is stuck open and a heavy rain comes, I'm given a puddle of water in the passenger side floor mat.
heater core may be leaking or hole in floor
Is it blood, oil, water, or urine?
There is a drain on the outside firewall that is clogged.
I had the same problem with my caprice a few weeks back. The water shouldn't be dripping from the back, it should be dripping on the rear passenger side floor board. That is caused by the heater core being bad, which is causing the water to seek through the carpet and drip out the back floor board.
