I have a 2008 RAM 2500 with the 6.7 Cummins. My AC/Heat only has a high and low setting, and the middle two settings do the same as the low setting. I replaced the blower motor resistor, and it worked for a month or two. Then i replaced the resistor again along with the blower motor, and it worked for 2 weeks and is back to not working on all settings again. What could be the issue? The truck only has 53,000 miles.

A lousy blower resistor.
