What's wrong?
The fuse block assembly in the battery compartment on 2015 Mci D4500, D4005, D4505, and D4000 coaches supplies and protects the circuit for the passenger compartment heating, ventilation, and air conditioning motors. A fuse block is the connection point that holds the fuse and power terminals. When it is built correctly, the fuse protects the wiring and motor circuit if electrical current exceeds the circuit limit.
On these coaches, a nylon washer was installed in the wrong place. It sits between the terminal and the fuse block instead of between the terminal and the power stud. That placement keeps the fuse from protecting the circuit, reduces the clamping force at the joint, and leaves less metal-to-metal contact at the terminal. The weaker connection can create localized heating at the terminal.
The driver can notice the passenger compartment heating or air conditioning stop working. That loss of cabin climate function is the warning sign tied to this defect.
Who's affected?
Spans four Mci D-series bus models from the 2015 model year, all tied to the same wiring component.

What's the safety risk?
An incorrectly assembled fuse block can leave the circuit unprotected and allow electrical arcing, increasing the risk of a fire. Loss of passenger compartment heating or air conditioning is the warning sign to take seriously. Schedule the repair soon. Repair is free at any franchised Mci dealer.

- Contact a franchised Mci dealer to schedule the free fuse-block assembly replacement that restores circuit protection for the HVAC motor wiring.
- Bring the recall notice if Mci mailed one. If not, reference recall number 15V580 when you call.
- Avoid operating the HVAC system until the repair is complete if the coach shows smoke, a burning odor, or electrical arcing.
