Almost every time I accelerate from a stopping point I hear a water/sloshing noise coming from the dash. It has been happening since late last summer (so almost a year). I tried to unclog the water drain (under the windshield wipers) with a coat hanger from up under the truck. Not much came out, just a little bit of debris. The noise remains.

Also is a creaking noise in the dash now. Almost like a fart noise, or old house wood floors. What could that be?
Any ideas help. Thanks.

 

Your drain is still clogged.

As for the noise, it could be any number of things.
