I actually have a subscription to ALLDATA, and the only info it has says it’s under the passenger seat. You can actually see where it would go, but it’s not there. The glitch in the system is the GM Vin decoder at dealership parts departments shows this part belongs on the truck, but if the truck has cooled seats, it’s definitely located in another location, if used at all.
Has anyone had any luck with this? 14 LTZ with heated and cooled seats here. Cooled seats work fine and lights for heated buttons work, but no heat, bottom or back either seat. Purchased module, but was not found in either seat.
