In the middle of doing this and have come to a stand still. Trying to remove the HVAC box and it's not moving. The motor is attached with clips at the top and the lower half is just a groove that it sits in, correct? Everything is loose. All the heater core lines are off, the AC dryer is removed, wiring is out of the way. The top half of blower motor is un-clipped and loose. The entire assymbly can be moved left to right at least an inch. Is the motor glued or something to the HVAC box? Any advice will help.
