I have a problem with my CLK320 aircon in that, for about five weeks now, I have been getting no air from the vents/outlets. It doesn't matter whether the A/C is on or off, or whether it's on Manual or Auto. The fan runs fine, but there is virtually no air exiting - UNLESS the Recirc button is pressed. I then get air from all vents as normal!
Now, I know this doesn't make sense. I know that all the Recirc button does is move a flap to take air from inside rather than outside... But this is what happens! You can hear it very clearly, too. Without Recirc, the fan is running, but quietly; press Recirc and you can hear the air coming from the vents though the fan speed doesn't change.
My local Benz experts have had a look but can't explain it. It doesn't help that, on rare occasions, everything seems to work OK for a few minutes and, of course, these always coincide with the time I take it to the repair shop! This is why I have discounted a blocked filter (for the moment, at least!)
But I am not imagining this. I have undertaken several long journeys recently and suffered very cold feet due to lack of heating. From time to time I press the Recirc button and get some warm air into the car, but you can't run all day on recirculating air.
Does anyone have any idea what may be causing this? The diagnostics show nothing wrong, apparently. I am baffled.
