I have a 99 GMC Z71 (new body style), I am having trouble with the 4 hi & 4 low on my push buttons, you can hear the transfer case working when you push the buttons but the frount tires will not pull. The 4 auto workes just fine. I have already changed the swich in the dash. any other suggestions...
