Car Forum / Ford / Ford Trucks / November 20062000 f350 diesel 4x4 and OD PROBLEMS
hi all my ride, 2000 f350xlt crew cab shortbox, 4x4. the problem, no response with 4x4 switch. i have read about the vacuum lines but when i move the switch there is no noise at all, no pop, no hmmm or clik. anyway to test the switch. i have checked hte fuses. the OD switch seems to have packed it in. it workled like a charm forever. then suddenly not working. are these related in anyway. i took apart the column and checked the wires from teh switch as i read that sometimes they get cut and short out but they are fine. thanks Biff > hi all > [quoted text clipped - 3 lines] > lines but when i move the switch there is no noise at all, no pop, no > hmmm or clik. anyway to test the switch. i have checked hte fuses. Does the 4x4 dash light come on? If not, your transfer case shift motor is not working for some reason. Only the hubs require vacuum, the transfer case is shifted with an electric motor. If it's the switch, perhaps it will work when shifting to 4wd low. The transmission must be in Neutral and your foot on the brake to shift into 4Lo. If not, perhaps power isn't getting to the switch, or the shift motor is toast, or there is a bad connection. This is one of the reasons I prefer a manual lever instead of a switch, even though I have an F250 and an Excursion, each with the damn switch. > the OD switch seems to have packed it in. it workled like a charm > forever. then suddenly not working. are these related in anyway. i > took apart the column and checked the wires from teh switch as i read > that sometimes they get cut and short out but they are fine. The OD switch and the transfer case are independent. Could be switch, could be the TCM, could be a bad transmission solenoid. Good luck. hi matt no dash lights come on. they do cycle on when the truck is started. but they dont come on whne turning the switch. 4 lo is a no-go as well. i locked the hubs manually and turned the front drive shaft and hte tires turn. vacuum lines look intact but i havent prformed a soapsuds test. isnt it safe to think that if hte lgiths dont coe on it has to start at the switch? why dont they have a manual override on these friggin things.? teh od i havent been troubel shooting as much but i will get back > > hi all > > [quoted text clipped - 23 lines] > The OD switch and the transfer case are independent.

IIRC the sensor for the 4x4 light is in the transfer case, so for some reason the transfer case is not shifting. > i locked the hubs manually and turned the front drive shaft and hte > tires turn. vacuum lines look intact but i havent prformed a soapsuds > test. At least the hubs can be locked manually. As I said before, the vacuum applies only to the hubs, not the transfer case. > isnt it safe to think that if hte lgiths dont coe on it has to start at > the switch? Perhaps. A bad switch would prevent the shift motor from shifting the transfer case, but so would a bad connection, shorted wire, bad shift motor, etc. As I said above, the light on the dash is not controlled by the switch, it is controlled by the transfer case. I would take a look to see if the electrical connector at the transfer case is loose or dirty. > why dont they have a manual override on these friggin things.? Because most people think "easier" is "better."
