There are two main reasons that You're going to have Your vent selector stop working on You in a 2008 Dodge Ram. The first reason is going to be because the blend door actuator has failed. A replacement will cost between $20 and $40 and You should be able to install it Yourself in about 30 minutes. The other most common reason will be from the vacuum line becoming damaged. This will be a bit harder to fixAnd is likely going to need the help of a mechanic.
