My Celica is leaking, Water soaking the carpets...help please Options

[circuscatch85]

My Celica, primarily in the colder months (but it does happen in the summer, too), seems to let in water. The carpets in the two back seats and the passenger carpet all get soaked, but not the driver's side carpet. I also get a lot of moisture (it even forms water drops sometimes) on the inside of my front and rear windshield. I know the obvious answer is that my car is leaking in water, but i had my mechanic look at it and he didnt know what was causing it. I'm just wondering if any of you guys have had a similar problem or might know what the cause is, thanks in advance

Do you have a sun roof? If so make sure the drain on it is not plugged. Might be a longshot but better to rule it out as one less source
