Exclamation 1996 Climate Control "Popping" Noise

Hey everyone!

I have a set of twins... 2 1996 E320's- (white and green)

My white E320 has developed a popping, almost hissing, type noise that is intermittent. It comes and goes every 20 seconds or so and is feignt to hear. It comes from the passenger-side front of the car behind the center console and is driving me NUTS! It sounds like a release of pressure, air, or something!!!!! I have isolated it to the Climate Control as the noise does not occurr with the System off. Blower works fine and doesnt make any noise. The pop/hiss noise does not get louder or become more repetitious as you turn up the fan speed... I can't figure it out!!!!

Anyone have a similar experience? My Green 96 is flawless, other than a new spring perch replaced by Mercedes under warranty (but thats for another post )

All thoughts greatly appreciated!
