Question about Ford F-150
I was told it could be the 4x4 modules,or actuator
What year F-150 , does the light on the dash blink ? could have a code set in smart junction box ( ford's BCM ) body control module . Actuators at front wheels are vacuum controlled , you can test to see if there is vacuum at the actuator. There is also a solenoid on the firewall near the battery that supplies vacuum to the front actuators !
