I cannot stress this point any more--do not remove the bolt under hood first and rotate the steering shaft around. If you move the steering around after removing the underhood bolt, you run into the problem of breaking the SIR coil in the steering column. This is the reason for setting the wheels straight before you begin. This would put the bolt head in an accessible position. It is for this reason that GM has a special tool to lock the steering wheel in place.
As I stated in my earlier post, since having the intermediate shaft replaced on my 05 Sierra 3500, some of my LED's for the steering wheel radio controls are not working. Could this be related to the SIR coil? I had GM replace this shaft and have had no steering wheel control LED's on the bottom of the wheel since. All the functions of the controls seem to work normally, just no LED's on the bottom controls. Can someone explain what SIR stands for?
Thanks in advance
