How many hours does it take to change the heating blend door actuator?

What is your question?

There is only heat on the drivers side, not on the passenger side. Purchase a blend door from the local parts store but could not change it because of it's location. Is there some special procedure to gain access to the heating blend door? Don't want to spend $300 in labor to change a $27 dollar part.

What makes this problem better or worse?

Noting; it is always like this.
