Mine was doing the same thing and I went to the dealer twice and even made them compare to other trucks they have replaced the blower motor and still the same drives me crazy! I read on another forum that someone else had the same issue and never really noticed it till they added slush mats which seems to reflect the sound I also have OEM slush mats and after thinking about it I started to really notice it around the time I put those mats in. I am going to try and make some foam or carpeted panel to cover the motor or was thinking about Dynamat.

 

Go to dealer and see if other trucks are loud, mine seems fine nothing different than any other vehicle.

 

I had a few minutes to take a look at it today, part of the noise is the blower motor vent leaking air, making a hissing sound. I took the motor out and made a foam gasket to seal that off better (self explanatory when you take the motor out). That took the annoyance out about 25%, the rest is in the dash and the motor bearings/brushes. I could have swore there was some foam soundproofing around the motor, may have been anther truck I was ling at.

A plastic/foam hush panel under the dash like most cars have would make it a lot quieter. The blower motor is plastic and where its mounted it just really seems to be loud on the lower speeds, more then any other car/suv/pickup I owned recently,

 

Any updates on the excessive blower noise? Anybody have it fixed?

 

I listened to 5 other trucks and they all do the same thing, it just bothers some and not others I suppose. Bothers the heck out of me but I cant imagine the dealer doing anything about it except replacing the motor.

 

I've been unhappy with my 2010 dodge ram 2500 since day 1 and hope chrysler goes under as a result of their "cutting corners". When I pay $52k for a vehicle, I expect a $52k vehicle, not a $30k vehicle, with the other $22k going to the UAW!!!

 

X2!!!!!!!!!!!
