Default 06 avalanche 4wd problems
2wd and auto 4wd seem to work fine but 4wh hi and 4wd lo do not. when 4wd hi and 4wd lo are used there is no power to the front transfer case. Any idea what the problem might be?

Very possible it’s the switch on the dashboard. A Chev dealer should be able to run diagnosis. The fact the Auto 4 x 4 Auto works is encouraging.
