Mechanic's Assistant: Have you checked the fuses? The dashboard bulbs?

Every thing works in the dash the indicator light on the switch shows nothing at all

Hi my name is ***** ***** I will be happy to assist with this today.In some cases I may need more info to assist better.I apologize for any delay.

If you did not have the transfer case control module programmed this can cause the issue you are still seeing now.It has to be programmed once it is installed which usually requires a GM dealers computer to do this programming.This usually takes less then a half hour for a dealer or repair center with access to programming to do this.If this was already done and the issue remains let me know.

If more help is needed, use the reply tab to continue our conversation. If no further assistance is needed, kindly rate my service,your 5 star rating is appreciated ( should be a link to click on here or above).You can rate at any time and we can continue to work on your question as this will not close out your question.Keep in mind in some cases it can be difficult to fully diagnose or help repair your vehicle without seeing it and I work on delivering the best possible answer from what I see to work with.

Thanks Pete
