Do seat blower fans really need to be programmed?

[2Cool2Fool]

I have a 2016 Yukon SLT with ventilated (heated & cooled seats). The ventilation blower fan in the drivers seat (back) is dead - and it's not a wiring problem. I located the correct replacement part (GM Part # 84206625 - $115.00), but all of the sites selling the replacement blowers have the following caveat: " This part requires programming and/or special setup procedures. GM Service Information describes the procedures and special tools needed to ensure proper operation in the vehicle."

I'd like to hear from anybody who has replaced one of these fans. It's hard to believe that a ventilation fans needs to be programmed by the dealer. That will turn a 15 minute $115.00 repair into a $350 bill.

Thanks
