Service Information

This bulletin is being revised to update models and model years.

When diagnosing battery draws on vehicles equipped with the automatic dual zone HVAC controls (RPO CJ2) technicians should keep in mind that the control head does not completely "go to sleep" until after 150-250 minutes or up to 4-1/4 hours, from when the ignition key is turned OFF. This is a normal condition. In these cases DO NOT replace the control head.
