has anybody ever seen this:
One day you get in the car, you last drove it in 2wd hi. None of the lights tell you what mode you are in. No big deal, dead light bulb. Drives normal.
A week or so later you get in, start it up, ALL modes are lit. Drives normal.
A week or so later you get in, no lights.
Finally you start pushing buttons. Now the car is in 4wd lo and won't come out of it.
Computer shows no error codes.
Mark X on hood. Bang head. Blazer is still broke.
