Another suggestion

" Its actually hidden away behind the heater motor, right hand side of passenger foot well where the carpet meets the bulkhead just behind the foot blower."

AND

Take a look at this picture. From a Corsa C. The Tigra B was based on a Corsa C. Hopefully resistor/plug in same location.

I learned many , many years back when serving my apprenticeship that the people who designed cars never had to work / repair them .
