Heater blower always on full power

Hi there.I have a 1991 Brougham De Elegance. Whenever the ignition is switched on, the heater blower blows on full power, weather the heater isswitchen on or off.I have put the problem down to the relay. Can anyone tell me where this relay is located, or is it down to a power module. If so, where is this module located?
Cheers,
James.
