What's wrong?
The A/C evaporator on the 2025 Thomas Built Buses Saf-T-Liner C2 is part of the air conditioning system that helps cool air before it moves through the bus. This recall involves buses with the evaporator installed behind the driver's seat. The evaporator's electrical ground cable is supposed to give the A/C circuit a stable path back to ground, which keeps current flowing through the intended wiring.
On affected buses, that ground cable was loose or improperly installed during manufacturing at the station that handled this A/C configuration. A loose ground connection creates extra electrical resistance. That resistance turns electrical current into heat at the cable connection, so the ground cable can overheat instead of carrying current cleanly.
The warning sign is an air conditioner that does not work or works only intermittently. If the A/C cuts in and out, report that symptom when arranging the recall inspection.
