Service bulletin SB 3083

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

NHTSA's summary

This Service Bulletin informs affected customers that MCI was notified by Mobile Climate Control (MCC) regarding a potential issue with the wiring in the condenser compartment. The absence of heat shrink on a crimp connector in the condenser compartment could result in corrosion of the wires on model year 2012-2013 MCI J4500 model coaches, and that MCI has a retrofit kit available for purchase.
