here's a video of the procedure:
I posted the Youtube video right above the pic of the AC amplifier in my earlier post which I guess the OP did not view. The ML amp is in the passenger quarter panel which the OP was talking about.
The picture of what would be exposed during a cabin filter change by the mechanic is the point I'm cheering about as the OP is confused on multiple things. He's also confusing ac amp with ML amp. It doesn't help that the ac control module is called an amp, it just lends to his confusion. Why is it called an amp as it doesn't amplify anything. That's rhetorical btw.

Is it because they don't want to warranty the service? Hold the BIG AUTO button and the recirculate button while starting the car and keep holding them until ALL the AC lights start to flash before letting them go. The display will give you 2 digit codes if anything is wrong with the servos. 00 means everything is working properly. You can ignore 21 24 and 28 because they are solar sensor codes and if you run the test when it's dark it sets them off.
