No Cruise, Blinkers, Partial loss of wipers-Check Park Aid Message.

[Tabitz]

21 Explorer XLT 29,000 miles, out of nowhere, received a continuous Check Park Aid message accompanied by a loss of all cruise function, Loss of Blinkers, Wipers only work on High, and possibly a few other items. Also received a Park Aid Malfunction message in my Ford Pass app. Did a cursory visual examination of the bumper sensors, fuse blocks, and visible wiring for signs of damage with nothing noted. Took it to the dealer. Any thoughts or ideas?

Welcome to the Forum.
There is a good chance that a trouble (DTC) code was set that the dealer can check for. It would provide a basic start to what the issue is.

If you have the camera in the windshield it could be caused by that going bad or blocked. That camera is connected to adaptive/intelligent cruise control, lane centering and rain sensing wipers.

Cars been at the dealer for a week. They are tracing the wiring. Suspect faulty connector or rodent damage. I’m thinking rodent damage as there are lots of mice, squirrels etc in my area. No warranty for that I guess

If it is rodent damage it is like from mice as there have been several reports of that. You are correct that the warranty doesn't cover that.
Let us know what they find. Thanks.

Still working it, but here are pics of a nest in the car. The said they use peanut oil based plastic insulation on the wires. Makes great sense.

A while ago I had a nest in the cabin air filter of my 2020 Aviator and a dead mouse in the HVAC fan causing a very loud noise as the fan speed was increased. My vehicle is garaged when home.

It was a wire damaged by a mouse. Dealer was able to repair. Works good now. $$$ ouch

Sounds like you need a cat or two.
