Date: May, 2014
On some 2014 Corvettes built prior to April 5, 2014, the heated seat may turn off within a few minutes of being turned on. It can be turned on again, but may turn off again by itself. This condition may be intermittent, depending on the seat’s position. DTC U1524 (Lost Communication with Seat Heating Control Module) also may be set.
This condition may be caused by a pinched wire in the seat assembly. Inspect the seat cushion and seat back heater element harnesses near the rear inboard corner of the seat assembly. It may be difficult to access this area without first removing the seat assembly from the vehicle.
If the harness is pinched, repair the wiring, reroute the harness and use a tie strap to hold the harness away from any pinch points.
