Heat will not blow on driver side

My van is blowing heat wonderfully in all areas except the driver side. Air is nice and cold but no heat. I think just from Googling that it is the blend door actuator. I have never fixed anything on my car but I feel that I can do it. I only have a couple questions.

1. If it is in the driver side would the part be the one on the driver side or the passenger side?

2. Do you access the driver one from inside under the steering area similar to the passenger side one?

3. Will I get electrocuted? Lol

Thanks!
