1997 manual, no aircon.
Hi. I have a cabin heater problem which by googling seems to be down to a faulty duovalve. My Haynes manual says to replace it undo the 3 hoses... pictures around the web seem to show 3 hoses. But my valve seems to have 4 hoses. Do I need my eyesight/counting skills testing, or do I need to hunt for a replacement 4 hose valve?
