2000 Pontiac Grand Prix GT SE from North America
Great car, and would buy again!
[1999-2003 PONTIAC GRAND PRIX LEAKS WATER PASSENGER SIDE]
Dealership said first the windshield was leaking; replaced, still leaked.
Next was passenger door weatherstrips; replaced, still leaking.
Next they said window passenger side leaking; wrong, replaced, still leaking.
OK, here it is, I found the leak myself, and it cost me about ten bucks. First remove the windshield wipers. Below the windshield is a cowl panel (screen) that you must remove. On the passenger side of the cowl, you will see a square opening that has foam sandwiched between two plastic pieces. Take waterproof silicone and seal all foam inner and outer surfaces. What happens is the foam drys out and shrinks, then water gets in and goes in air box and drips on the passenger floor. Let it dry and reassemble.
The 3.8L engine is known for reliability and over 200000 miles.
Would you buy another car from this manufacturer? Yes
