F-53 Cruise Control Issue

[Iowa Boy]

I have 2021 F-53 and had Liquid Springs (ft&rear) upgrade installed and now cruise control is dead. Ford Truck dealer and Ford engineering can not come up with fix. Have replaced steering wheel components, etc . Did not ever see “service advancetrax” message, etc. Worked for first 8,000 miles now inop. Anybody else have this problem??
Note: Liquid Springs made big improvement in ride and handling.

Probably no help to you since yours is so much newer than several I have worked on and probably already checked, but I’ve had the cruise control stop working on my 2007 Town car, 1996 F53, 1997 E350, when the trailer lights fuse was blown.

You might also try pulling up on the brake pedal with your foot, or checking your brake/cruise switch adjustment. I have the same problem with our ‘02 Workhorse and have both read of and had the issue on all makes/models of vehicles.

I’m sure the problem is coincidental with the Liquid Springs install.

I'd be looking at the antilock wiring in the back, where they worked.
The speed sensor is part of the same system.
