Ironhead729,
I would like to apologize for the issues that you are experiencing with your Sierra. Have you had a chance to take it into your dealer to have them look into this for you? They may be in the best position to assist you in getting this diagnosed for you. Please keep me posted and if you have any questions please feel free to contact me anytime.
Thank you,
