This unit is fitted in my five year old swift escape 664. The blower fan only works at one speed regardless of regulator setting. It used to sped up on the 'A' position until the thermostat setting was reached

Any ideas as to where the fault may lie?

    Obvious cause would be a faulty switch. They seem to be about £30 on the internet. You could try removing it and use a meter on it to see if you can work out how it works. Also check for loose wires. Don't forget to take a few pictures so you know which
    way to put the wires back on.
