Chevy Blazer Mechanical Whine
I tried backing my Blazer out of my driveway in 4
WD Auto, but the engine just revved and emitted a
high-pitched mechanical whine when I tried
reversing. Didn’t move, just revved and whined. It
seems to go forward fine without the whine, but I
only inched it forward, I didn’t drive it a long way to
test that. I tried putting in in 2 HI, tried in 4 HI, but
only whined. Any ideas what went wrong and/or
how to fix it?
