How do you change blend door actuator on a dodge Dakota?

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.
