I haven't driven my truck for 4 days and it was covered in snow and I started it and it sounds like running water right on startup. And there's water on my drivers seat on the door panel and the driver side grab handle help! I got a video of the water Sound. I don't know how to upload it though

 

Heater core and leaking windshield.

 

ah.. Those were my fears. I got a picture of it I don't think it's the windsheild
