2011 Infiniti M56: Climate Control Volume?

May 27, 2011


Despite what the picture above may be alluding to, no, you cannot adjust the volume of the M56's climate control. But I wish we could. You see, as I was stuck in bumper to bumper to bumper to bumper to bumper traffic last night (should've taken the Harley home), I noticed a weird whistle and hum.

Initially, I thought it was the big delivery truck next to me, but the noise persisted after he crawled a few car lengths ahead. I turned off the climate control and it was silenced. I turned it back on and after a few seconds, the noise returned.

The noise is coming from under the hood, not through the vents, thankfully. Once you get past 35 mph (which pretty much never happened last night), it becomes less noticeable. But it's still loud enough to hear when the radio is on while you're stopped. To me, it sounds like something's wearing out, almost like a chirping fan that used to be inside my old (first-gen) plasma TV. The climate control still works as it should, though, so perhaps this is just something to investigate the next time it's in the shop.
