Sounds like the Heater Control Unit. Metal box about 10cm square above the passenger foot well. A known source of trouble. Mine used to give me intermittent cabin heater/fans or sometimes fans that would not turn off.

Should be easy to get to, just find it and unplug the multi-pin electrical connector. Some people on the forum suggest sending it way to have a duff connection repaired. I took mine apart and cleaned up the circuit board and removed any corrosion from the contacts (internal and external). I also found a very small piece of solder, about 1mm round, that was stuck between two contacts. It must have been rattling around shorting across various connections.
Thanks mate i will give it a clean up tomorrow.TVR's do so funny things.
