When turning on my heat last weekend on my 2012 Ram 1500, there is now a loud humming or buzzing sound that comes on. Sounds like the blower. If i crank the heat at high settings it gets louder. The sound is coming from the passenger side behind the glove compartment. I have tried all settings and still the noise is pretty loud. Has anyone had this issue and confirm if it is the blower?

Had something similar to what you are describing a while back. Turned out to be the cabin fan, (passenger side behind the glove box). I took it to the dealer, they heard it and replaced the fan which fixed the problem. Took them a couple of hours to replace, and it was under warranty.
