[s-cars] Squealing crickets associated with HVAC system

I'd be reluctant to shoot oil in there unless I could see where it was
going. You might end up with an "oilman's air freshener" as the fan gently
wafts the odour of the oil through the cabin.

Thanks, Fred.  That's what I was suspecting it was.  I wonder if a 
good shot or two of Kroil down the hole might help?
