Vibrating centre console
just a quick question, I'm wondering if this problem is all just in my head. It seems that over the last week or so when I turn on the heat (most noticeable on defrost or high setting) in my 84 500SEL, that there's a vibration coming from the centre console. I usually rest my right leg against it, and it definitely seems like something is moving. Theres also a noise that accompanies this vibration, low pitch, hard to hear unless you're listening for it. I was thinking maybe blower fan bearings, but that's just a wild guess. Anyone have any ideas on this?
Thanks in advance.
