#715 of 886 high pitched whistle by engineman

Nov 09, 2007 (4:39 pm)

I just purchased a 1998 c280. It's my my first benz and so far am pleased with it. I was wondering if anybody knows about a high pitched whistle that comes from the climate control. It doesn't happen all the time but it is quite bothersome. It is not caused by the fan because it does not get loud when I turn the fan on high. It lasts about 2 to 10 seconds. Some times it lasts only about 1 to 3 seconds. It seems to die down after the car is warmed up . If anybody knows anything i would appreciate some help with it.

I can only speculate....and my speculation is that the whistle comes from the system trying to close off the outside air [recirc mode] and not getting a good seal. To find out, try hitting the recirc button when the system is otherwise quiet, and see what happens. This would be independent of fan speed, as you've already noticed. Otherwise, I'm clueless...

The air conditioner often comes on when it completely off.
Sometime when I used the automatic, it would run about a minute or two then stop.
Mercedes Benz has changed air conditioner relay and air conditioner blower it still doing the same thing.
I need to know if anyone of you has ever experience a problem like that C240 03.

This week I took my C230 MB to the dealership for tune up it was due for. Car runs great, never problem. I was told the front coil springs were broke and lower control arm bushings are well warn. Which does not surprise me the car is almost 8 yrs old. The MB dealership mechanic said not to be concerned with them right now but they will have to be fixed eventually. How long can I wait before fixing them and what will happen if I wait too long? Will it ruin something else on the front end of the car?
thanks

The front coil spring (strut spring I presume) is BROKEN? Really? That's something that needs to be fixed....like yesterday. You could snap a strut.
 
Control arm bushings may not be urgent, but they could eat up tires if they were really bad.

directions are listed in your C-Class owner/operators manual.
Under the category Operation: Flexible Service System
I have a C230 yr 2000 and my directions are listed on page 84
here is the directions for 2000 C230,since yours is two yrs newer than mine it may not help you but it may help someone with same yr as mine:
1. turn electronic key in steering lock to position 2
2. within 4 seconds press button "0" twice. "located on dash just below +,- buttons"
3. the present status for days or distance is displayed.
   within 10 sec turn electronic key in steering lock to position 0.
4. Press and hold button "0" while turning electronic key in steering lock to position 2 again. The present status for days or distance is displayed once more.
Cont. holding button "0".
after approx 10 sec a signal sounds, and the display shows 10,000 miles for approx 10 sec.
FSS now is reset.
 
It took me a couple of trys to get it to work and reset my FSS.
