The thermostat on my 1998 Ford Explorer has had to be replaced for the second time in two years with no definition of why it has broken.

The blend actuator door is stuck in the open position which means that I can't set the temperature in the passenger compartment to a comfortable level. After searching this problem on the internet it's apparent to me and others that this has got to be a defect based on the number of complaints.
