so my air conditioning makes a loud poping/clicking noise whenever the defrost is off. I can actually see part of whats goin on. When the defrost is on some lever behind the stereo is moved up and its fine, when the defrost is off then the lever goes down but kinda gets jammed i guess. I dunno its incredibly hard to figure out whats goin on down there. anyone had this prob?

 

Mine kinda pops and clicks sometimes, but I can never tell what it actually is. Only happens when the AC is on, so yeah, its that. Doesn't seem to affect anything though, so I'm just leaving well enough alone.
