I have 2019 ford raptor with 60,000 easy road miles. Never had an issue until a few weeks ago. When I turn on the interior electrical fan for the ac/vent or heater the dash 2x4, 4x4 hi low switch flashes on and off as does the indicator light next too the mph meter inside the dash. Even more strange the over head cabin switch go bright thwn dim in rythum with the fan motor. The truck toggles between 2x2 and 4x4 transfer and doesn’t know when to position itself. If I turn off the interior fan all suddenly remains calm and back to normal.
One shop couldn’t work on it because they didn't have the necessary computer so now I have an appointment with ford dealership in two weeks.
Can anyone help me? I greatly appreciate your expertise and advise. Thank you jim
