We get an intermittent rapid light tapping noise from the right side of the dash when the A/C is on. Any ideas as to what's going on?

either you hear the a/c pumping, or the bearing on the clutch assembly is going out.

Debris in the A/C filter or blower area?

Wouldn't the sound of the a/c pumping be continuous? This is an intermittent rapid tapping. And isn't the clutch assy on the compressor, at the front of the engine?

Did some more searching, and figuring out the cabin filter hasn't been changed in 110,000 km (ok, flames on), I'll change that and drop the fan at the same time. Maybe a leaf or tree needle is creating that tapping noise.
