Water on Carpet on Passenger Side
 

My passenger side carpet is wet with water. I don't know where the water came from? Some said it was probably water trapped after the rain showers? Any idea? Is this bad?

Yes it is bad, it will mold if you dont clean it up and dry it out.
Check your A/C drain tubes, crawl under the truck and on either side of the bell housing will be 2 drain tubes, clean them both out.

I had that same problem before too. Check you're windshield seal. I've put some silicone sealant on it and now its not leaking no more.

9 times outta 10 its gonna be the A/C drains clogged up with gunk.

crawl under the rig. on either side of the tranny housing there are rubber nubs. clear those with a nail or even your fingers.

wear eye protection cause water with gush out. about a gallon will pour out.
