Whistling HVAC System?
My wife told me she has got a couple of whistles the other day, I laugh, sorry I did, then she continued. The whistling noise was when she was driving the 400E, and came from inside the cabin. Yesterday when we were driving I heard the whistle noise (about 1 to 2 seconds) and I believe its coming from the HVAC system. When the noise occurred, I thought it happened when the air distribution was changing in the center vents. A vacuum leak?
Thanks, enjoy your drive, timreid

Did you ever find the source of the whistle? I am going to look at a co-worker's 97 E320 in a couple weeks. It suffers from something similar, and I believe it is coming from the HVAC unit itself, which I know is big $$$$. I plan on poking around with a MityVac. Any suggestions for where to look? It's definitely manifold vacuum related because it cycles on/off when throttle is applied at varying rates while driving the car.
I know this is one of those things that could take 20 minutes or 20 hours to find...

I'm having the same issue with my W210. A very soft whistling or squeaking noise coming from the climate control vents. Only occurs with the A/C on. Doesn't happen in EC mode. Noise is very intermittant. Usually lasts 3 to 4 seconds at a time. I've had it to the dealer but they could'nt replicate the noise while it was there. Doesn't appear to be a squeaking blower motor.

I have had this whistle for about a month now. I thought at first it was because of a leaky vacuum hose in the trunk, however that is fixed now, and it still squeals/squeaks continuously. I do believe mine also stops when the controls are turned to Off.
I'm curious as to what this might turn out to be!

I had a similar problem in my e320 BUT it would only happen when one or two of the dash vents were partially or fully closed. Check your vents, make sure they're open (at least to test the whistle).
