4x4 broken

[Jasun26]

I need some ideas to fix my 4 wheel drive. I have a 03 excursion. When I turn the switch nothing happens. Checked the fuses, and replaced the transfer case motor. I had the motor unbolted and turned the switch to 4 high and nothing happened. Going to get the volt meter out and try to track down the problem. Wondering if anyone has had similar issues. Could use ideas where to start. Thanks

It's probably and inner axle seal or possibly a torn vacuum hose. Don't let somethin seemingly very complex let you overspend trying to fix something simple.

I replaced the inner seal and packed the front hubs with grease. Wouldn't it still work if I manually locked the hubs? I can't get the 4x4 light to come on. I took a wrench and manually turned the transfer case shaft the motor turns and the 4x4 light lit up. My next guess is to get the volt meter to check the 4x4 switch works.

If the hubs are maually shifted it should work if the tcase is in 4bi. Could be in the switch then I guess.... or somewhere in between which would suck

That was the nightmare that woke me up last night. I know the switch will work fine. Haha

Jasun, it's been a couple weeks, what did you end up finding? As bad as you thought?

I had to take it to a local garage to find the problem. After a few days and several issues it's finally fixed. The new transfer case motor is no good after a bench test. There are two relay switches to turn the motor clockwise and counter-clockwise. The guy found out there was a cut somewhere in the wire harness from the clockwise switch and runs to a box on the passenger side behind the glove box. My options were to have him open up the harness to find the cut OR just solder a jumper wire to the wires and bypass the harness. The guy asked if I wanted to do the work to save some money. I center spliced the wires and soldered new wire on. It actually works now. The guy only charged me 169 bucks for a lot of head scratching...

Hopefully you are still around, but can you elaborate on what you soldiered? Maybe post up a picture? I am having basically the same issue. Flip the switch,and nothing happens. The 4x4 just doesn't work at all.
