I just noticed--(could have been there a while)--that at high blower motor settings--espicially on recycle setting--the blower motor is making a growling noise. It is almost like the motor is really working hard. The noise is not normal and has never happened in my previous GM trucks/suvs.


I am wondering if the techs have seen this before. I have not taken my truck into the dealer since purchased last Nov--and I am planning on taking it in for a list of items. Any heads up prior to the dealer trip would be helpful.
