Question about 2005 Chevrolet Avalanche
Four wheel high works and auto four wheel works
Try shifting the shift selector into Neutral first then try engaging 4wd low. If that doesn't work try shifting into 1st gear and then try engaging 4wd low. The information is inside your owners manual but if this doesn't work please let me know. Also is the light on for which mode your truck is in (2wd or 4wd high)? If not, you may want to check for a blown fuse.

SOURCE: four wheel won't engage
Theres a vacume dash pot under the battery box. It pulls a cable that engages the front diff. Put the vacume line and you'll have lights and four wheel drive. (it happened to my blazzer)
