To be able to diagnose this properly, you would need a scanner capable of scanning more than just engine codes and also show live data of what the transfer case is doing. Is the service 4x4 light on? Likely there is a code stored for the problem and would point to what is going on. My money...

Nope. Just let 'er rip. No. The shaft and actuator are keyed to a specific position. The gear might have skipped or slipped internally. https://gmtnation.com/forums/threads/hvac-actuator-noise.19130/#post-569144 And then there's this video. Very descriptive however his are slightly...

Check to see if you can see one in front of the radiator/condenser, like in the pic in that other thread. That's where it's usually mounted. Or check to see if the cooler line was split to another cooler. That's usually done near the radiator's cooler lines. Trailer tongue weight is usually...

AFAIK, none of these trucks ever had a factory installed auxiliary cooler. We always recommend adding one no matter the tranny or engine. This thread has some info: https://gmtnation.com/forums/threads/transmission-coolers.9702/ Depends on the tongue weight and how much the truck squats with...

Nice! Post up some deets and pics. They are rare birds indeed. Hope to see you around.

You might need to do an HVAC relearn. Pull the HVAC-B fuse for 30 seconds in the rear fuse box, put it back in, then turn the key to RUN but don't start it and don't touch the HVAC controls. Let it do its thing for a couple of minutes while it relearns the actuators. If that doesn't work...

I doubt those would affect the interior lights as they are isolated from the BCM by relays. A broken wire in the steering or the clockspring? Check the schematics and check the wires going into the steering column. Other than that, I have no idea what could be causing your issue.

We have multiple sources for manuals online, including downloads of a bunch from my own site. Need GMT360/370 Service Manuals? Get them Here! Then there's Charm and Lemon which are copies of actual factory manuals.

Just adding info on the newest site that has ALL manuals for all brands and models up to 2025 (currently). https://lemon-manuals.org.ua/ https://lemon-manuals.la/ https://lemon-manuals.gy/

Playing devil's advocate here. DOD/AFM can be disabled and can extend the life of the cam and lifters. They usually fail when they're deactivated and fail to reactivate. My son's 2012 Silvy with 5.3 still has the AFM hardware but has been tuned. Never opened or replaced anything, all...

Were the map lights replaced with LEDs? I know in the GMT360 they cause a funky issue similar to yours but only affect the map lights (turning on map is dim until you flip the visor to turn on the mirror lights and it becomes bright). I believe it's something to do with the BCM because the...

The FAQ is your friend, specifically the one for Drivetrain. There is a link to an article on ORTB that has all the info you need on the disco: https://offroadtb.com/4wd-disconnect-rebuild/

:duh: Missed that this was on a Silverado because I'm just so GMT360 oriented. Did you follow the instructions from a manual...

Don't forget that you can get the actual manual at https://lemon-manuals.org.ua/

Welcome! You definitely picked up a nice low mileage TB. Even the headlights are clear! Nice examples are getting harder to find as the last one was made in 2009, not including the current model made by Daewoo. Enjoy!
