I have noticed that on my W140(300SD) two things about the AC..1)it does not seem to blow at a high max speed.....2)When accelerating with the AC I sometimes hear a whistling sound coming from the ducts...the air blows very cold and does not change volume when the whistling occurs...buts its an annoying sound.My 1992 300D 2.5(124) never had this whistling problem and also blew at a higher max fan speed. Took it to the dealer once for this at the last oil change and they said it didn't seem to be blowing quite fast enough but didn't really see any problem...any ideas?

Your blower problem is the blower resistor #140-821-83-51 almost every 140 have this problem.

You can order this from us and do the job in under an hour...I have heard of the dealer charging upwards of 4. Be carefull.

The whistling noise is probably from vacuum leak, should not be there at any time. Take car back & have them RIDE with you when problem happens.
