Hello, the blower fan motor on my 1997 Legnum is failing to come on when demanded by the control panel. It works sometimes, but now mostly not! I've a feeling it's probably the heating control module, but would like to check the fan is ok, by powering it directly, or if indeed the controller is giving it power. Does anyone have the wiring info for this part of the car, or any experience of this issue? Thanks guys!
