Hey all, I used the search but couldn't find a problem quite like this (go figure). Every once in a while when I turn my TB on (03 LTZ ~190000 kms) I get the Service 4WD light, and none of my options light up on my dial (usually the 2HI is lit up obviously). Also I can't switch to anything but the 2 HI I'm in. Hasn't happened to me for awhile, but we're on a trip through the rockies yesterday and kept pulling off to take pictures, this happened after one of those restarts. I figured it might have something to do with the fact that I'm obviously pushing the tranny a little harder with all the inclines and speed changes. But then to get the problem to disappear, I pulled over, stopped, shut off the vehicle, pulled out the key and opened the door so that everything shut down. While it was off I flipped my drive dial back and forth a few times (between 2HI/A4WD/4HI/4LO). Back in to 2HI and I started up again, things are normal, Service 4WD light is gone. So I'm wondering, perhaps this isn't something very serious with the 4WD, but more so with the electrical or even the dial itself? What would be the best course of action to diagnose something like this? I very rarely use the 4WD beyond winter driving, and even then I don't use it a ton, but I definitely want to know it's working.
A little bit of recent history on the TB, I bought it March 2011 and shortly afterward I took it in with some 4WD problems, turns out they had the wrong type of fluid in the transfer case, the previous owner's backyard mechanic didn't do enough research. So all of my fluids are now good and the parts should be in good working order. I'm hoping it's electrical and ideally something to do with that dial in the dash, because that should be a simple enough fix I think.
Elsewise the TB's running great, I need to do a couple of fixes (heated seat elements, cluster motors are shot for the oil pressure and temp gauge), but nothing serious. I switched to AMSOIL this year and with the help of this site also diagnosed and replaced my water pump in the spring. Definitely still enjoying becoming a TB owner!
