Passenger side. It doesn't seem very difficult at all to replace. Here's a writeup on it-

went to 2 dealers to pick up the actuator and they're useless....nobody knew which of the 4 listed actuators controlled the driver side vents nor where they were located....all i got was a diagram of the whole system and the prices (apparently 3 are identical and $280 ea. and the single different one is $85) all they kept saying was to remove it for the part number....i would if i knew which one and where it was.... i refused to purchase either without knowing which one i needed....from the diagram its very hard to tell which one controls the driver side vents and defrost.....anyone know which one it is or the part number?? id hate to have the dealer do it and pay them to do something i can do....thank you....

bump to help this guy....mine might need replaced soon too

thanx narco...the write up link chauncey0337 posted is good but nobody can confirm thats the actuator that controls the driver side vents and defrost....and from the diagram the parts guy at the dealer gave me it looks like the furthest one from the vents im trying to get open...and if its the more expensive actuators its like a $600 job at the dealer....id rather not experiment....lol
