A no start condition on some 2025-2026 Acadia, Traverse and 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.
For more information, refer to Bulletin #26-NA-140.

Umm… NO it wouldn’t.
the fuse is “protecting” the ground of the relay coil which would not be sensitive to the load of any device that is operating on the contacts of said relay.
The KR27 Starter Relay and KR7 Rear Window Wiper Motor share the F17UA Ground-Side Relay Fuse. An open fuse could result if the wiper motor draws excessive current from binding in the motor or a bent wiper arm, which may also cause a no start condition. Wiring schematics were incorrect for several models and have been updated. The Service Information schematic for 2025 Acadia will be updated soon.
i found the diagram, 26 chevy traverse, the diagram is correct as you see it, that fuse is between the ground g114 and all of those relays. doc id 6821536. would be nice to have an explanation as to why the change?
what what blows the relay if its on the ground side? where did you get this diagram? just looked up 25 gmc arcadia and there is no fuse f17ua associated with the rear wiper! the only way that fuse would blow is a short to power, and if it was after the fuse, the wire would melt first.
F17UA is on the ground side of the relays. The 2024MY does not use F17UA for relay grounds. The change was made for the 25MY.
I’ve got the same question as Neal.
so this fuse is on the ground of the relays…??
