Over the summer my fiancee had to push my dodge ram up a hill. He had to put it in 4 wheel to have enough power. We got the blazer home and shut it off with the 4x4 still engaged. The next morning, no 4 wheel drive. Press the button for 4high or lo and it blinks and clicks but doesn't engage. Vacuum lines are all good as is the module behind the passenger kick plate. Help!!!!!
