I have a 2003 Alero 2-DR Coupe ... When it rains I get water leaking into the driver's side under the steering wheel ... inside the plastic paneling. The carpet is gets completely drenched. And the water shorts my fuse box causing my car to act with a mind of its own! Radio comes on and stays on after ignition turned off ... volume and signal variable ... dashboard light icons will come on randomly ... e.g., oil icon and battery/electrical icon ... For the past 2 days we have had heavy rains in Reno, NV and the short was bad enough that it drained battery completely. It is the same prob as mentioned on this site at: http://www.fixya.com/cars/t824745-weather_related_electrical_problems I would appreciate very much any guidance you may offer ... Tku.

Re: Water Leaks 2003 Alero
YOU MAY HAVE A LEAK AROUND THE FRONT WINDSHIELD. CHECK THE RUBBER MOLDING AROUND THE GLASS. YOU CAN SEAL IT UP WITH SOME SILICONE AT THE EDGES. IF YOU HAD A WINDSHIELD REPLACED TAKE IT BACK AND THEY WILL PROBABLY TAKE CARE OF THIS FOR YOU.

While H3 is parked on driveway, driver floor mat is removed, and steering turned all the way right to expose splash area, pressure hose the front left steering splash area behind left tire while another person feels with their hands to determine where water is entering. If the leak is beneath, it would only enter when you go through flooded area. When it rains, the water constantly splashes behind the tires, which is an area source for water to enter the driver area while the vehicle is in motion during rain condition. If you live in snow area, they use salt to keep roads clear of snow. Salty water is highly corrosive to exposed steel. In the summer or fall season before snow begins, you steam jet pressure clean the underside, then inspect for any area where undercoating had come off. Take primer spray paint and cover these exposed areas with at least 3 coats of primer paint, or rubber sealant spray.
Have your windshield gasket checked. When it rains, and if there is a small hole in the gasket, water will travel around the edges and down the inside. It will flow behind the dash and finally onto your floor
NO, it is most likely getting in through the cowl vent area under the wipers. Normally the water drains out the inner fender, but if its clogged with leaves and pine needles, it wont drain and will fill up past the cool air intake and get into the cabin. I would pull the cowl vent grille and make sure the drains are not clogged.
These water leaks can be really tough to find. In some cases the windshield seal can be leaking and the water runs down the firewall into the interior. I have a similar issue on my Aurora from time to time. I believe the issue is the weather strip around the door seals. It looks to me like the water follows the weather seal and then is wicked into the car where the carpeting contacts the weather seal. I have thought about putting small holes in the weather seal on the bottom edge (facing the exterior of the vehicle) so that the water has a path to follow out of the car. Not sure if this will work.
SOUND LIKE RAIN WATER LEAKING BY WINDSHIELD BE LOW COWL.YOUR LARGE RUBBER SEAL THAT GOES BELOW COWL AREA ACROSS BACK FIRE WALL IS EITHER DAMAGED OR MISSING ALLOW RAIN WATER SHORT OUT ALTERNATOR OR WATER LEAKING THROUGH WHEEL WELLS SHORT OUT ALTERNATOR AND GETTING ON FLOOR BOARD CHECK UNDER THE CAR AT THE WHEEL AREA YOU SHOULD HAVE A COVER PANEL AT WHEEL AREA TO KEEP WATER FROM SPLASHING ON ALTERNATOR GETTING ON INSIDE VECHICLE ALSO.
First I would check and see if its leaking for the front window.take a water hose and spray water around the seal of the window and see if it leaks. If it don't then I would take do the same test around door seal and the passanger side window.
In the dashboard,set down low is a driptray.It collects water that comes off the aircon.It has a hose (sometimes 2) that drains the water out of the car via the firewall so it drips onto the road.This is blocked or the tray has a buildup of gunk.The hose is about 1/2 inch thick.If you lay on the floor where it leaks with a torch you should find it.Or look in the engine bay,just to the left or right of centre(which side leaks?)and backtrace it into the car.You may find the inside hose has fallen off allowing the water to drip inside.Hope this helps you
It sounds like a plugged drain line from the air conditioner. Most cars now run in the a/c mode whenever u turn on the climate control (even when heat is on). The passenger side front is where it would be wet, and the carpet and carpet pad act like a sponge and will soak up the water. Let me know how u make out.
