if it has a plug, connectors, wires, is removable, it can be checked, tested, wiggled, poked, cussed at, removed and replaced, etc,
thanks for the help, and the challenge!!!:icon16::icon16::icon16::icon16::icon1 6:

just an update. thanks to your giving me the location of the onstar battery, i was able to chase the wires and connectors and ground. saved myself a lot of time at the dealer as the connector/ground wire were somehow loose. it now recharges and passes dig's.
sometimes it the little stuff, even in these times of whiz bang electronic's.
thanks again for your help;:icon16::icon16::icon16::icon16::icon16:.
