running a/c in winter
I understand that the a/c should be run once in a while in winter to
keep all components lubricated, and so on.
Just yesterday the weather here (in Canada) was getting warm enough
to do the winter "a/c work-out". When I push the a/c switch,
nothing happens. I mean absolutely no response at all; no red light
indicating a/c is selected, a/c clutch did not move at all, rpm of
engine remained unchanged, the "rec" switch did not change the vent
I did not know what to do.
However, a few hours later when I started my car again and tried the
a/c unit, guess what, everything kicked in as if nothing had happened
earlier - indeed that was the case. The a/c seemed to work fine.
Could someone explain why ?
The only speculation is that the compressor or the condensing unit
may require certain warm-up after a prolonged period of inactivity.
Before the warm-up is complete, the unit won't start. Am I close ?
