Service bulletin SIL-3143

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

Altec has learned that a 12-volt Airtronics relay installed in the PDM could have been manufactured to an insufficient threshold on certain units built from December 2004 to October 2022. This can cause the relay to overheat and fail, causing the accessory lights to stop working.
