Majik 0 Posted January 14, 2004 Hi mate, welcome to the forum Ok it could be either the eariler slider control or the late rotory control. If the slider/knob feels like its resisting the cable could be jammed. If the slider works ok then one of the ducts which carries air from the heater motor to the dash vents could have come apart, it would be easier to show this on a diagram if anyone has one. Shut off the front facing vents, this would cuase pressure and make the air try to escape through the windscreen vents. (as long as its in the windscreen position) if a little air comes out then you will know its the cable not operating properly. Im not too sure how much a cable cost but it can be replaced quite easily for this you will need to undo the four screws iether side of the heater control unit.
