ECCU BLOWER MOTOR - 1998 V70 T5

I have developed and intermittent problem with my HVAC blower motor. On average the blower will not come on at one of every 10 starts.

I have checked the fuse. I have adjusted the ECCU settings into "manual" and cycled both TEMP knobs as well as the air location distribution knobs. This has no effect.

Sometimes the blower will start, if I turn off and restart the engine one or more times. Other times, this will not work.

Has anyone else had/solved this problem?

Is there a relay in the system, which may be the culprit? Might it be the blower motor resistor? Is my ECCU beginning to fail?
