    Default 05 Yukon 4wd problems

    The "service 4wd" light stays on and sometimes it shifts itself into 4 low. Any ideas?

    I would start with the switch. If you pull it apart you may find some bad solder connections.

    I'm finally getting back to the Yukon after just pulling fuses. I got the back of the dash switch off and don't see anything wrong, time to dig deeper

    You might need to open the switch and check for bad solder connections INSIDE of it.

    I did that, that's what I meant when I said I got the back of the switch off. Apparently you cant take the circuit board out

    Had the transfer case oil changed and the problem went away till the wife put it in 4auto. The light came back on a while later and it shifted itself to 4low.
