^^^ Nailed it! ^^^

If you have any electrical issues with a C6 the first item on the list is to make certain the battery is good and the computer has been reset.

With the new head unit and if the battery tests good, I’d look for a pinched wire. Start at the ignition switch first and work back to the head unit. Since it works correctly on ACC but not on RUN, could be an issue where power was connected to for the head unit. You didn’t say but does the head unit work correctly in either switch position?

okay - replaced the battery with a new one. Connected the cable leads together while I was at the store (to reset computers). installed and wired up - Issue still present! I read a post from few years ago that this same sequence was happening to another C6 and he brought it in and they checked the window switch. Determined it was bad and ordered a new one. That DID fix the issue. I will likely do the same. Question is, how is the switch checked to determine its bad? It would be easy to see if it worked at all or not but how to tell when its not working correctly, I don't know. Any help is appreciated...

webdzynes

yes it does. All worked fine for about 2 months. Then for no apparent reason, this started...

I'm wondering if I can pull the window switch and just disconnect it to keep the window up all the time until I have the time to work on a fix... Will a disconnect mess up other stuff?

ohm meter will be your friend. Test the leads of the switch to see if they change states. If not, the switch is faulty. Check to see if power is getting to the switch, or to the circuit.

You need an old priest and a young priest. Or a new battery.

webdzynes

Got the new battery...
The priests wouldn't come over...

But since the battery didn't work, I have finally purchased a new passenger window switch. Let's hope that does it!!

webdzynes

Thanks everybody!! The new switch did the trick!

Good. Now remove the Z51 badges (it's an option, not a model), so nothing else goes wrong on the car.

Well, technically so are Z06 and ZR1. They are all RPO codes.

I'm waiting for cars with Z07 badges to show up at the car shows next.

Glad you figured it out, and we were no help at all.
