MB 1998 SLK230 One owner, kept in garage, very little driving, short trips. Problem: We are getting an intermittent, high pitched sound coming from the middle of the dash board. It lasts about five seconds, then goes off again every thirty seconds, It does this when the air conditioner is on or off, and also this heater on or off, however if we hit the EC button, with the system on, it stops the sound. There is nothing in the manual. Any ideas where to start to solve this problem. (EC is economy mode)

Thanks

If this is a whistling sound you are probably having issues with one of your blend doors not fully closing. Tell me, if this is happening and you change the direction of airflow to say your feet does the sound go away? If it does then what is occuring is one of the doors that directs the air is leaving a gap which is causing the noise. Kind of like closing your lips and whistling.
