All u need to do is change one actuator....the one that he showed u on the internet. Do not get confused. It is really simple. The most difficult part was accessing the 3rd screw....just remember to remove the bolster underneath the bolster...then access should be easier. Watch the video until the very end again. He omits one part of the removal but reminds to explain the second bolster at the very end.
Number 1, this is the worst job to do on this car hands down. Its near impossible to get up there to that thing.
That being said I got the new actuator in. And I still have cold air most of the time. It will click over sometimes, doing a little better than before, but definitely not consistent.
Do you know what exactly the 3 actuators do independently? are they all 3 exactly the same(part number wise)? would replacing the lowest one still possibly fix this problem or do I have something else going on?
