furnace motor

my furnace blower motor runs at all times and will not shut off
it is a 2 speed motor
i was told my fan-limit was shot, but when the furnace goes the blower goes to high speed and then back to low when done
the have the same unit next door, but single speed motor and it works fine
any thoughts?

it is a clare furnace about 12 years old
thanx ryan

sounds like it has been wired that way to run low.

Is there a switch on the side of the unit saying blower on/off?

Is it on AUTO at the t-stat?
