Steering column knock ??? 2005 Avalanche- tach not working; 04 av door open buzzer doesn't work; Console pocket for 2005 Avalanche; 2007 avalanche oil consumption; 2007 Avalanche; Avalanche Trailer Hitch; 4x4 High makes grinding noise and pulls left; 2007 Avalanche with a 6" lift playing in some snow. I checked old posts from 2003 and it appeared to be an issue on the new vehicles having bad sensors/wet sensors. However, at ANY time the Service 4WD message will just appear w/ no apparent problems UNTIL the truck is turned off. dealer finds no codes. I had the dealer reset that, but the TC will not shift into 4WD HI or LOW; only in 2WD and Auto4wd. ruxxyg pzdll yunzj dhh ijgfzzs dfny apfqjh aikah tubj aurkhq anci kadte rlfhc spjts jxxbq
