What's wrong?
The HVAC blower motor circuit in the 2019-2020 Mercedes-Benz Sprinter (VS30) powers the fan that moves air through the heating, ventilation, defrost, and air conditioning system. The wire harness carries electrical current to that blower motor, and the fuse is supposed to protect the circuit by opening if current rises above a safe level.
On affected Sprinter vans, the fuse layout for the interior blower motor does not meet the required design needs. That leaves the blower motor circuit with inadequate protection, so the wire harness can overheat during operation. The repair changes that circuit with a new and relocated fuse and a new supply line.
When the issue occurs, the driver can notice unusual odors inside or near the vehicle. Treat that smell as a warning sign that the blower motor circuit or wiring area is getting too hot.
Who's affected?
Includes both Mercedes-Benz and Freightliner Sprinter (VS30) vans, with the same wire harness tied to wiring and HVAC blower-motor components.
