2002, Honda Civic SI: heater fan stops working episodically with no pattern. It's not a fuse, or the blower motor or the switch control panel, the latter having been replaced and the motor tested (they were going to put in a newe one but testing found it worked). I've taken out the relay and put it back in, but not replaced it. The fan works, then stops, then works again. Any diagnostic ideas that I can pass on to the techs at Honda who appear to be stumped? All speeds work or none work.
