The patience you exhibited there, by waiting 2 and a 1/2 weeks before posting, is highly commendable. However, there must have been some kind of action going on, possibly not easy to identify (lack of a visible krausen, a subdued fermentation) but nevertheless present. Airlock activity, whilst fun to observe, isn't a reliable indicator to guage fermentation. Time to get the hydrometer out and test a sample as that's the best way to assess how your fermentation has progressed.
Certainly a bit strange that, at the temps you mention, it wasn't a faster and/or more dynamic fermentation.
