Well, V2 is the blower motor itself of course and the Ros-Tech Wiki states:

Possible Causes
Fresh Air Blower (V2) defective
Control Module for Fresh Air Blower (J126) defective
Short of open circuit in wiring to Fresh Air Blower (V2)
Climatronic Control Module (J255) malfunctioning
Considering the motor has just two connections, the only way the controller could possibly sense something is wrong is by monitoring current-flow (unless air-flow is somehow measured, but I doubt it's that sophisticated).

So the fault code probably tells you no more than you already knew, that there is an intermittent fault causing a break in the current-flow. Probably a bad connection, as you say, but is the bad connection in the wiring, the "hedgehog" or the motor itself?
