I know there are tons of threads on this already, but I am not sure there is one measuring decibels. I brought my Heep in 2 weeks ago to see if the Dealer could fix the loud AC, thinking they would do the TSB I have been reading about. Nope. They changed out the blower motor....

Guess what. The problem is not fixed, I think.....

So here we go. I downloaded a random Decibel meter app and tested it. Anyone else want to download an app and test theirs for comparison?

2018 JLUR 3.6L
(holding mic next to center if grill)
AC on setting 2 and recirculating - DB reading 75.7, 75.7, 76.6
AC on Max and recirculating - DB reading 94.7, 94.9, 94.6

So almost an increase of 20 decibels. That cannot be right, right?

You must have done a very poor job of explaining the problem to them. The blower motor is in the dash...

I agree, but my exact worlds more or less were when I turn the AC on above 3 the “outside” fan sounds like it wants to take off like a plane.

The techs notes state that the blower motor was cutting out and noisy. Back I go.
