    Hi guys, your assistance would be appreciated. In the last few months my 407sw 2.0 petrols heater box has been blowing cold with no adjustment available. This I could cope with as I figured one of the heater flaps had snapped. We still had a bit of warm air so no big deal. However in the last week the heater motor decided to only work on 1 speed. And today has packed up completely. I have heard mentions of resistor failures and power feed problems. The display still shows all speeds, but nothing from the fan. I have checked fuses.and connectors. All seem OK. Any ideas what to check next would be most helpful as I cannot even demist the windscreen. Cheers. Hornet.
