Seat control switch module D is the fourth switch unit in this series; no manufacturer documents U0272 publicly or says which seat it belongs to. Such switches need not sit on the seat at all. On 2021–2023 Escalade, Tahoe, Suburban and Yukon with the power-folding third-row bench (RPO AS8) the folding switches are in the overhead console and command the K169 folding third-row seat module; GM later dropped their red latch indicators (PIT6041). Jeep has technicians let a Grand Wagoneer third-row seat relearn its end stops by pressing its switch twice after the vehicle has been off for two minutes (9100364). So check the seat module and its learned state as well as the switch. If switch D falls silent, the seat it serves can no longer be moved from there.

Likely causes

Wiring to a switch mounted away from the seat (console, roof, trim) interrupted
Seat module lost its learned positions or needs new calibration
Switch module D without supply or ground
Switch module D internally faulty

Symptoms

  • Rear or folding seat does not respond to its switch
  • Seat stops short of its end position
