I think I have a problem with the Aircon on my 1998 W140. Whilst it does get very cold and very hot as it should, it only 'blows' well when I select the 'recirculate' option (when the red LED is on). When I turn off the 'recircuate' option to draw air in from the outside, after a couple of seconds, I hear a flap move and then it sounds like it is trying to suck air through a blocked pipe?! This noise appears to be coming from the passenger footwell...
I have recenlty had the carbon filter replaced so I know that's not blocked.
If anyone knows what this problem is, I would love to hear from you.
Also, the rear air vent always blows cold, even when the front is blowing really hot. Is this normal?
Many thanks,
