Heater/Ventilator fan - intermittent

P reg 1.9 TD SX Estate: fan works properly most of the time, on Full/Auto or Off as required. But recently it has been going intermittent on me. It does not appear to matter what the cabin temperature is, and it happens with or without the aircon switched on.
Any ideas anyone?

You can start by checking if there is power at the fan unit when it goes intermittent - in which case it's the brushes.

Many thanks, but to date it only happens during a journey, which makes investigation a little awkward. My Haynes manual doesn't tell me the way in to the fan unit. Any hints?

Further to all this - towards the end of a long motorway journey on Sunday, with the aircon ON (and working!) and the fan on Auto, I bagan to feel cold so switched the fan to the Off position. It just carried on running, and no matter where the control lever was it continued running on low speed until I arrived and switched the ignition off. Ten minutes later I had to go out again and lo and behold the fan responded to its controls.
This would seem to indicate that the fault is not with the brushes. Thermostat or switch itself perhaps??
