What's wrong?
The HVAC blower motor circuit on 2016-2020 International Transtar, Durastar, Prostar, Lonestar, Workstar, and Hc vehicles powers the fan that moves heated or cooled air through the cab. A wire terminal inside the power distribution center connects that circuit to the main cab harness. The terminal has to carry steady electrical current whenever the blower runs.
On affected vehicles, the supplier used a terminal that fit into the terminal block but was not rated for the continuous current load of the HVAC blower motor circuit. Under blower operation, that lower-current terminal does not handle the electrical load as designed. Heat builds at the connection instead of passing through a terminal sized for the circuit.
There is no warning sign before failure. The owner notice does not identify a noise, message, smell, or fan behavior to watch for before the terminal overheats.
