After getting battery jumped, no window indexing, radio won't work
I'm sure someone's asked this before, but how do I get things back to normal after jumping the battery.
Went away on a trip and came back to a dead battery. Car runs now, but the windows won't index and the radio / dvd won't come on.
Any hints or links to stickies would be great

seconds after window is up, release switch, then hold up for
another 3 seconds. Do each window, one at a time.
This sets the indexing.

could it be the battery's too low and needs charging still?

the radio has a theft code set. if your not the original owner and know what the code is that was set in the radio, then you will have to visit stealership and have them reset it for you.
when ever the car loses power you will always have to reindex windows and put rhe theft code in the radio if one was set.

I would try disconnecting a battery cable for a few minutes and let it reset everything. Hook it back up and then try to re-index the windows. If it doesn't work then the battery may still be too low like AORoads said. Put it on a charger over night or replace it.

As mentioned, window indexing is very simple, as did it when replacing the battery. Didn't have any problem with the radio, as the original owner, and never set any theft codes. I'd be more concerned about the battery. If it was drained down to zero, then probably a goner, and needs to be replaced.

A dealer can use a Tech2 to force the radio to "re-learn" the VIN number to clear a Theftlock condition.
If you are not getting a Theftlock message, I suspect you have some kind of power problem, such as a blown fuse.

I don't believe our radios have user settable codes any more. Modern GM radios "learn" the VIN of the car via the data bus the first time a new radio is powered up in the car and stores it. After that, the radio compares the stored VIN number with the VIN number on the data bus each time it is powered up. If the numbers match, it operates normally. If the numbers do not match, such as if radio has been swapped from another car, the radio displays "Theftlock Activated" and will not operate.

Add another possibility to your list.
I had this problem, & found this thread via google. I tried the reindexing thing, but nothing happened.
I checked all the fuses & made sure all the relays were set properly... nothing.
I checked my battery connection, it was loose. I tightened it up & everything worked right away, no indexing needed.
Thanks guys.

Just a piece of advice. Modern cars do not like jump starts as they create power surges that can fry the internals of the many computer modules, of which the C6 has a ton. Tread carefully.
