2004 Trailblazer dash cluster noise on 2004 Chevrolet Trailblazer

I took my blazer in because my instrument cluster failed, they replaced it, and we noticed around 1500rpm it would make a noise I can only say sounds like a cow mooing. We complained, and left our TB with them for over a week, and they say they tried 6 different instrument clusters and all of them made the same sound. I find it hard to believe that all GM remanufactured insturment clusters make the same sounds. The sounds is driving me nuts, any answers?

was this done at a dealership or indendant shop? i have never seen this b4
Dealership. My husband thinks they did not try 6 different ones. They just said they did. We can't imagine 6 rebuilt clusters all making the same noise. My friend was the one that came up with the mooing, but she is right, sounds like it is mooing.
YA OUR DEALERSHIP DOESN'T STOCK ANY OF THESE,ONE DAY SPECIAL ORDER AND THEY ARE R/B ANYWAY. I FIND IT HARD TO BELIEVE THEY HAD 6 IN STOCK. I CALL BULL. TAKE IT BACK AGAIN AND INSIST ON SATISFACTION
