'04 Yukon XL, 8.1, 27k miles. Noticed this morning that my transfer case is in neutral, red light between "2wd" and "4hi" is on. When pushing the 2wd button, it just flashes then stops flashing and the red neutral light stays on. Does the same when trying "Auto" button. Truck drives fine, don't notice anything unusual.

Any ideas? Solenoid(s) bad?

Hope it's not related to the horrific GM transfer case thread below.

Doesn't have anything to do with the gm 263xhd t-cases wearing a hole thru at high miles. Without scanning it my guess would be a bad encoder motor or transfercase control module,your still under warranty I assume so take a trip to your friendly gm dealer,if it wasn't under warranty it would probably be about 500$ to fix it,Smitty

Thanks Smitty. We have a scan tool, check it tonight, Just out of warrenty though, under miles, over time.

Any thoughts on what makes the module or encoder motor go bad? Just unlucky?

It may just be a bad switch assy on the dash, a fairly common problem.

ThirdBird

That would be nice.

Not really sure why the encoder motors go bad but they have swi\tches,circuits and a gear drive motor that are hanging under neath your vehicle exsposed to temperature changes and moisture/salt etc. The most common part on these 4wd systems to go bad on the full size is the encoder motor,the modules rarely go bad (except on the older auto- trac mini blazers).The cheapest/fastest way to trouble shoot it is if you have a friend or relative who has the same vehicle who will let you switch the parts off theirs one at a time until you find the offending part because the encoder motors are big bucks-(300-400$) and only take 20 minutes to switch,dash switch is the same thing,takes 15 minutes to switch,I think it cost about 60$-80$ for one but if you buy one you own it,Smitty
