    Hey guys, I hope I am not wearing out my welcome with my second tech question. If anyone can help, I sometimes hear water (or some kind of fluid) that sounds like its slushing around under the dash. I have no in cabin drips or leaks. Not sure what it is and its not all the time. Any ideas?

    I had the same sound in my Suburban it turned out to be the leak detection fluid from the AC.:neutral:

    Man, I have never heard of leak detection fluid. How did you fix it?

    I've had the AC drained and refilled with new Freon.
    They put the leak detection fluid in when I had a leak then they can see the leak with a black light but I think they had put too much in it.:whip:

    Thanks TahoeFever, I appreciate that. Believe me, I will have more questions. I am just now getting to the upgrades stage so you know how that goes.

    14 for all that room. I should have got one of those. I am getting 15.5ish mpg and I drive 40 miles each way to work and have alot less room. YOu probably have the 5.3 right?
