So I started installing the A&A Supercharger on my 07 c6. After pinning the crank pulley, I started to put steering rack back. Because the steering wheel had moved when I disconnect the shaft, I tried to rotate it back to the same position.

Well, I rotated it too much. I thought it would lock as I rotated it, and the next thing I know I hear a pop inside the steering column. Remembering reading something about it from the instructions, I decided to go back and confirm. Sure enough here is the portion from the instructions...

So what is it (wire coil) that popped and anyone have a diagram where I can start taking the steeing wheel apart to get to it. This really sucks too because I was being really careful with eveything elses. At least I got the crank pinned, tap the oil pan and etc...

 

It controls all the electronics in your steering wheel (airbag, horn, etc. not to mention the possible option stuff) so you've got problems brother. I would slap it back together & take to an unsuspecting dealer & tell the had the wheel locked all the way & heard something snap & hope they're dumb enough to cover it under warrenty. Lol

Before I get flamed, let your conscience be your guide, you broke it, so it's on you, but my point is it's not a cheap simple fix.

 

If you broke the Clockspring coil they are not that expensive (at least the one I bought last August) - but not sure what a dealer would charge to replace it (labor cost). I did my own steering wheel swap on my 2005 (to the later 3 spoke wheel from the "doughboy" 2005 wheel) - that required an airbag change and clockspring coil swap (Coil swap reqd as airbag connectors are different on 05 vs 06+).
The Clockspring Coil was around $90 IIRC (aug. 2007 price from a forum dealer)
In addition to the steering wheel/airbag (natch), you have to remove the knee bolster and steering column covers to disconnect the coil wiring.
(2005 service manual was almost useless - even the column cover info was wrong, it showed 2 screws holding the Tilt/Tele model covers together - wrong, they just snap together...) I used care to reroute the new coil wiring and zip tied it in a few places (as originally done at factory)...

Personally I just pulled SIR fuse (didn't disconnect battery as some do) - and left it sit overnight (to make sure capacitor charge for airbag drained)
(even the printed GM 2005 manual inside fuse panel diagram was wrong btw...)

Coil comes with an install sheet (and IIRC the manual had the same info, or similar), but of course I didn't have to reindex the shaft... (although there's a dot on the shaft end (at the SW retaining nut end) at 12 o'c IIRC) I had wheel locked at 12 o'clock and just slid off old coil, slid on new one (and broke off orange plastic tab on Coil once installed).
I took a few pix when I did this and a member here also had some pix in an off-forum gallery.

 

Yeah, i searched last nite and found how to remove the Airbag..I just wanted to know exactly what is it that popped..I don't want to tear everything down too far when it might be something simple that broke.
