My Front A/C works great, but my rear A/C only blows air between outside temp and Hot Hot Hot. If i turn the rear a/c to full cold it is the outside air temp, if i turn it to full hot it gets very hot.
I referenced this thread below, which suggests replacing the actuator, but before I drop 90 on a new actuator I wanted to ask if a bad actuator would cause it to do what it is doing? Since it seems to work (heat is hot) could it not be that?

I notice that when i have the front and rear a/c 'on' the refrigerant line after the front rear split is cold for the front a/c and warm for the rear a/c at the splitter. Is this due to the bad actuator or do i have a problem in the refrigerant line? Any advice?
My second question is what the 'AIR' fuse in the under hood elec box controls. I inherited the car from my brother and the fuse for 'AIR' is missing. Anybody knows what this controls?
