Hello, my name is ***** ***** I am a professional here at Just Answer. I have noticed that your question was not getting a response and thought I would see if you still need help with this.I apologize for the delay and I hope I can still assist you with this here.

Chevy released a service bulletin back then that dealt with this problem and it evolved a wiring modification to the control panel . I have enclosed the steps for this repair in the link below. Copy and paste the link to your browser to open and view it.
