Most likely there's a leak at the bottom driver-side of the windshield. After the mat dries out, close the windows and concentrate a strong stream of water from a hose, starting with that area. If you see no leak, go on around the windshield a little bit at a time. Water can run from anywhere and drip down behind the cowl. I had the same problem. Two fixes. 1. Leak in the heater core or core in/out flex connectors. (replace it) 2. Blockage in A/C evaporator/condenser drain. (overflows into driver footwell. I had this problem with my 93 Corsica. A buddy with a 91 Beretta showed me it was the same problem that he had. There was a crack in the gutter where it is welded to the firewall as well as dried up sealant between the firewall and wheel well in the engine compartment. Try pulling up the carpet and underlay, in my case the water had come in and was running down the firewall behind the brake pedal but under the underlay. Here is a link to some photos of my drivers side leak: http://www.forthopetradingpost.com/corsica.html Good Luck!
Leak in heater core
Try tapping lightly on your cellanoid (located just under the front bumper on driver's side of center). MtLittletree55
in cup cause it smaller
He cause quite a splatter when he stomped on the rain puddle.
The movement cause by the kinetic energy is visible.
Too much exposure to visible light can cause damage to your retina.
i would say either a leak would cause a puddle underneath, or if you parked ontop of a spot of fluid that was already there before you arrived.
It sounds like you may have a bad heater coil. Next time you get a puddle, smell it... Chances are it is coolant and not water
Check the timing for the 90 Corsica. the most likely cause for the engine not starting is it has jumped time causing the engine to fire at the wrong time.
There are here in the UK. You cannot have any device that could cause distraction (such as a TV screen or laptop) visible to the driver in the front of the car. Mobile phones MUST NOT be used by the driver while the vehicle is moving (current penalty £200 AND 6 points on your licence).
Water may leak through a fan box on a Chevy Corsica if the water pump has broken. Another cause may be that debris clogged one of the drain holes.
Amateur with some ideas: 1-could be fuse in box under dash on driver's side 2-my trunk light did the same, traced wire that had worn in a spot from constant opening and shutting - could the headlight wiring have same wear and tear?
