    dashboard rattling

    yes, we've been using only chevy and gmc trucks since 1990, every one of them from then to now has some kind of rattling or tapping niose comming from the area where the dash meets the windshield, and only when the plow is on and only noticable when on the freeway, is that an accurate description? to this day its still a mystery.

    If it's with the plow on, sometimes there is a strange noise when the air comes up over it and onto the windshield seals. Mine did it when I had a bug guard on it. My dealer says that if you add anything to the front of them that changes the way the air moves over the hood you get that noise.

    When you buy a GM bug shield it comes with tape for the weather stripping

    I get the same thing with or without the plow. Only driving over 50mph. Sounds like a piece of something is stuck between the windshield and the hood vents, checked like 10 times and still find nothing. It bugs me

    Check the flaps by your hood hinges. If that's not it, I have a squeeky blower motor that annoys the hell out of me. The sound comes from under the passenger side dash.

    I also have an occasion dash vibration, sounds like an air duct or wire or something is loose under there. I turn up the Bose and ignore it.

    maybe its the radio, do you have a teenager who might have changed the station? The new popular music sounds like a buzzing or rattling.

    it sounds like it is coming from the gauges. As soon as I go the plow installed the sound immediatly happened.

    I have a noise coming from my dash but it is my speedo cable that makes the noise.Also my last truck made a noise it was the plastic around where the windshield wipers are mounted the platic cover rattled.It was becaus ethe way the air comes over the plow.I know what you are saying those little noises drive me crazy.
