No. From memory there are two yellow wires that come out of the back of the heater control unit that feed the blower motor relay. When I turn the control knob I get a whirring sound as the motor moves the lever to open/close the gates (disconnected on my car) and if the engine is not running I can hear the fan start. The whirring noise stops when the lever reaches the end of its travel. There are two micro-switches that control the movement of this lever. One of the cables was a bit seized (now fixed) so the rod connecting this lever to the cables would pop off. Now that I have freed the cable off I might try reconnecting the rod and see if it can open/close the gates without any manual intervention. But access is difficult to fit the rod and it's cold outside at the moment; when the weather warms up I'll try this out.
