when pressing my dash switch for 4 wheel drive I can her the switch or relay clicking but the green dash light stays off and the vehicle does not have 4 wheel drive, anyone out there with any ideas or useful tips to check please.
I have jacked the F78 up and checked for 4 wheel drive in 4H & 4L no drive on front prop shaft....now suspect it something to do with the Vacuum pipes and servos.....please any help or advise welcomed.
