Question about 1990 Pontiac Sunbird
Water seems to be leaking from under the hood into the front of the inside car. We pulled the plastic dashboard out a little and where the foam is on the dashboard water leaks in and goes under the carpet when it rains.
Well your car is 113 years old it's bound to leak somewhere, I didn't know they made sunbirds in 1900

On the passenger side, below the heater motor, you will find a rubber water drain hose. The drain is supposed to keep water from building up in the HVAC unit then leaking into the vehicle.
Generally over time, leaves, pine needles and other debris will plug the drain hose allowing the water to back-up in the HVAC unit and end up in the passenger compartment.
You may be able to get to it under the hood or have to crawl under the car to clean it.
Chances are you will find it plugged and causing your leak.
Good luck and let me know.

some cars have cabin air filters for the cliamte control system. It would not cause a leak. Look for a grommet loose or a seam leaking. Lift up the carpet and follow the stain to its source.

I had the same problem. This one is a little involved and not for the faint of heart. There is a drain from the sun roof which runs down the passenger side door. There is a rubber gasket just above the vanity mirror that joins a hard metal tube with a flexible plastic tube. Stupid design if you ask me. Anyway, if you remove the screws from the vanity mirror as well as the trim piece that runs down the edge of the door between the windshield and the door, you will probably see a piece of flexible tubing hanging loose. Slide the gasket back together and voila!! No more floods in the passenger seat. Once you have fixed the drain dry out the car with towels and a dehumidifier if possible. Throw a couple boxes of baking soda in (follow directions on box) and you should have a clean dry car in a few hours. I left mine running over night and was dry as a bone and no mold.
