Gotta diagnose and identify the cause of the problem before you can fix it. Otherwise, you just blow money by throwing parts at it until you get it fixed (if you ever do).

The blend door actuator on late model Dodge Durango and small pickup can be accessed by removing the glove box. There is a very common problem with blend door failure in these vehicles, and dash removal is required to perform the repair. A cheap and easy DIY fix for this can also be found at heatertreater. They also make a heater core regulator which bypasses the blend door and can remedy the situation with no dash removal.
