A no start condition on some 2024-2026 Acadia, Traverse; and 2025-2026 Enclave models may be caused by a rear wiper motor binding or a bent wiper arm. (Fig. 16) Fuse F17UA may power the X50A Engine Wiring Harness Junction Block, which includes the engine restart relay as well as the rear window wiper motor relay.
Fig. 16
If fuse F17UA is open, visually inspect the rear wiper’s arm and motor. If the arm is bent or the wiper motor is binding, it may cause fuse F17UA to blow, disabling the engine restart relay. (Fig. 17)

Refer to the appropriate Service Information to diagnose and repair any rear wiper arm and open fuse conditions.
