The ENTIRE dash board, steering wheel, center console, front carpet, outside windshield wiper mechanism comes out to do the job. The evap is behid the heater box - so the heater box must come out to do the job. As mentioned, replace all the vacuum actuators at the same time. I have seen my mechanic do many of these, and he can do it one "long" day if left alone. Unlike some, he puts all the parts back.
