Cruise control not working. Did self diagnostics. Got a flash on the off on button. But nothing on resume coast or set accel any ideas

 

Begin by testing for power at the master cylinder pressure switch.
Then test the switch for having open contacts.
Any leakage around the switch means replacement with only a Ford part..
Their should have been a recall mod done long ago that places a lower amperage fuse in line to prevent a fire issue.
The system power comes through this switch.
See what you have first.
Good luck.

 

changed out pressure switch. All is well
Thank you
