Swapped out the battery and all started, EXCEPT.
The Onstar never came back on. Nothing has changed except the car battery and I cannot get Onstar.
Can anyone tell me where the Onstar unit is and how I can check it or replace it without taking it to the rip off dealer.
For instance, they wanted $275 for the replacement battery that I got from a chevy dealer for $150.00.
I found a TSB online from Onstar that recognizes this problem and direct owners to the dealer for replacement. I never received this TSB notification. Can I still get it replaced under this TSB? Apparently it happens with enough regularity of there to be a TSB about it. The bulletin number is #09-08-46-004B. This has the EXACT problems I am experiencing.
