Stuck in 4-wheel low
Truck says it's in 4-wheel low on dashboard
however it was never put into four-wheel
drive at all. If you put it into 4 wheel High it
reads 4 wheel drive low and high. I don't
think that it could go 35 miles per hour if it
was truly in 4-wheel drive but it seems like
there is no power and I can't climb Hills very
well. The check engine light was on so kit to
get it diagnosed and it said something was
wrong with the vacuum. We've tried the
going and drive going in reverse and we've
also try disconnecting the battery which
seems to work temporarily and then it starts
doing it again once it's restarted. Any
suggestions? Could this possibly be just a
vacuum?
