What's wrong?
The HVAC linear power module in 2014-2015 Ic Bus Ae school buses controls blower speed for the heating, ventilation, air conditioning, defroster, and defogger system. In plain terms, it is the electrical controller that tells the fan how hard to move air across the windshield and through the cabin vents. The defroster and defogger depend on that fan control to keep the windshield clear.
On affected buses, a double battery jump start or an electrical load dump event sends too much voltage through part of the module. An electrical load dump is a voltage spike in the vehicle electrical system. That overvoltage overheats the module, and the module then fails instead of controlling blower speed as designed.
There is no warning sign before failure. If the module fails, the blower speed control can stop working, which affects defroster and defogger airflow when the driver needs clear glass.
Who's affected?
Both model years are tied to the same defroster and HVAC fan motor component.

The year and model narrow the scope, but the VIN decides. Check your VIN to confirm whether your specific bus is included.
What's the safety risk?
If the LPM overheats and fails, fire risk increases. Confirm your VIN and ask an Ic Bus dealer about the upgraded LPM replacement for this recall. Repair will be free at any franchised Ic Bus dealer once available.
What should I do?
- Check your VIN to confirm your 2014-2015 Ic Bus Ae is included in this recall.
- Watch for the Ic Bus owner notice if you have not received one, and keep it with your service records.
- Contact a franchised Ic Bus dealer and ask about the free LPM replacement that fixes the HVAC blower-speed module overheating risk.
- Reference recall number 15V242 when you call the dealer or Ic Bus customer service.
- Avoid double battery jump starts until the LPM replacement is complete.
What happens at the repair
The repair process identified by Navistar is straightforward. At the dealer, an Ic Bus technician replaces the HVAC system linear power module with an upgraded module. That module controls blower speed, so the work focuses on the part tied to overheating and failure after an overvoltage event. The dealer repair will be free once available, with parts and labor covered under the recall.
