Just purchased an 08 KK a few weeks ago and just trying to make sure it's ready to go for the winter. When I turn the heat on the blower is loud. Sounds almost like someone blowing through a straw. When the heat clicks on I can feel the Jeep shutter a bit at idle. While accelerating the AC compressor makes a loud whining sound increasing as acceleration increases. At idle the compressor is pretty loud. The heat blows very warm and seems to be working fine.

I am thinking of replacing the blower motor because I think that the bearings have worn. Anyone have the acceleration issue? I'm thinking the AC compressor needs to be replaced. Or maybe the drive pulley. Any help is appreciated.
