2005 GMC 2500hd left side...
2005 GMC 2500hd left side seat control, when I press the forward, the seat goes back, and when I press the control to go back, the seat goes forward. I install a new switching module and the same thing still happens. What could be wrong?

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.
I am here Sundays through Thursdays from around 5 am to 2 pm Mountain time.If you respond and I do not respond back right away I will do so as soon as I can.

This was a common problem.The fault is in the seat control module located under the seat itself.It tends to reverse the signals like you see here where it causes this fault with the seat control module needing replaced.Now in some cases a GM dealer can reprogram the seat module to correct this but in most cases it has to be replaced and programmed.This has to be done by a dealer as they have access to GM programming to program it whether they just reprogram it or have to replace and program it.

If it only needs reprogrammed your looking at about an hours labor or $100.If it has to be replaced this can run around $300 to have replaced and programmed.

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.I work on delivering the best answer and help here but in some cases, it can be difficult to do without seeing the vehicle.

Thanks Pete
