my non intermittant part of the wipers was in fact the column stalk.
But, as you have the wiper out I can heartily recommend you take the wiper apart, clear out all the hardened grease and put fresh grease in there on the plastic wheel, and the metal motor 'corkscrew', plus check the brushes and lightly emery (finest grade) the commutator.
It is not a bad job at all. You need just a T20 torx bit. The plastic cover (where the electric wires are soldered) just unclips (4 clips)
I have a lot of photos of the insides of the motor if you want a link.
Please post photos! (Perhaps start a new thread.)
I suspect that those motors are basically the same across all generations of Spiders and thus will be helpful to many of us.
