I have a 2005 C55 AMG that I purchased in Nov 2005. Now that it is hot in Texas I am running the AC lots. When on high I notice a loud whirring or turbine sound when standing outside the car. It is only slightly noticeable from within the car. Is this a normal MB thing or should I be concerned?

If you have the climate control in AUTO you will hear the loud whirring noise outside. I usually don't hear it when it's in the manual climate control mode. For the most part it is normal.

Sorry to resurrect this really old thread, but has anyone figured out what this is? Its happened since I got the car but want to make sure it is not going to cause my a/c to go out.

I think is what you need...

Thank you for that KJB. Unfortunately, I have a question to ask: Are TSB's covered by MB or is it something we spring for out of pocket?

Out of pocket.

04 32 here, when I turn the ac on it doesn't kick on for a few minutes. It can also run fine.. then stop for a few minutes again. Cycling the key can usually recreate the issue. Any ideas?

No strange sounds.

What do you mean exactly when you say it doesn't kick on. Does it not blow air, blows warm then kicks in? Maybe the refrigerant level is getting low. If the pressure is too low the compressor may not turn on

pointman

Oh, sorry. Yeah, it does not turn on at all. No air is coming out. Then all of a sudden it starts working again. Its been this way for a while.. last two warm seasons. But after it eventually starts blowing air, it seems good until I restart the car again.

Sounds like either the blower motor or the blower motor regulator is on its way out.

pointman

Damn. Thanks for the info. Gonna try to get it fixed.

Any advice on about what I should expect to pay?
