[jake's7.3psd]

i checked for power at the switch but nothing there. also when i switch it to 4hi the dash light does not come on. no noise from the motor on transfer case. its a 2000 superduty free/lock hubs. i was pulling into drive and it worked fine turned it off went into house for 2 hours came back out went to put it in 4wheel again and it wouldnt work dash light wont come on or nothing will happen. checked fuse under hood. also checked 4 matching relays by fuse box under the hood. any ideas on what els it could be?

Pull the switch out of the dash and check the connection at the harness could be loose check all wires behind the switch for burning or signs of shorts.

Just recently went through the same problem... spent hours upon hours testing relays, fuses, tracing wires, etc. Got tired of doing all of that and took it in and had a computer hooked up to it and had a ton of codes for a faulty transfer case motor. New motor installed an all was well again.

Tap On the motor with a hammer,seriously, My 98 explorer does this crap all the time and a couple of taps and it goes on working fine, Im just too cheap to buy the motor for it.

when you traced the wires and stuff did you check for power at the switch? and what kinda power to what prongs thatks for the help

[slowridin03]

Mainly used an ohm meter to check the switch, relays and the motor. Once they all checked out, we had it put on a computer

In the transfer case motor assy there is a set of contacts that get dirty so the computer doesn't know what position it's in. There fore is just sits there and does nothing. I had this same problem before cause I don't use my 4wd very often. Take it apart, clean it and slap it back together. Bada bing bada boom.

I got into the habit of cycling the 4wd every now and then and haven't had any troubles since.

Good luck and let us know what you find out.
