Re: Safrane V2 1997 Climate/heater malfunction

Hi, you may have sorted your fault by now. But, if not: If the heater fan speed unit gives up it can cause the fan motor to only work on its highest setting (straight through unregulated voltage). If the motor itself is on its way out, the wiring can get quite hot and the plastic connectors sometimes melt. Try re-wiring the connector to see if it helps. Heater motor speed control units are a common fault on a lot of Renaults as are dodgy wiring loom connections. Corrrosion on the connector can also cause a heat build up and plug failure/meltdown!
