2003 S600 Rear AC Problem
So I've tried searching through the forums, Google, and a few other places, but I just can not find a solution to this.
On my '03 S600, the rear AC is spasmodic and I can't figure out what is triggering it. It seems to me like the blower motor is turning off and on.
There will be times that I'm parked and have the rear AC on and it will stay on indefinitely. But there will be times that it turns off and on in random increments while parked also.
While I'm driving, it seems like accelerating, braking, turning, or really any kind of body movement causes it to turn off or on.
I already had to tear the trunk a part to get to the air compressor for the air bladders in the seats that control dynamic, pulse massage, etc (Had to unplug and re-plug one of the boxes because none of those features on the front seats were working) and I didn't see anything that looked like an AC system.
I've also tried open the little "service box" under the rear AC controls. None of the wires were loose or disconnected.
Any help in diagnosing or fixing this problem would be much appreciated!

The closest thing I could find to malfunctioning AC is that the refrigerant is low, but the front AC works great and when the rear AC is blowing, it works great as well.
Not to mention, the AC light is NOT blinking
