My 2000 Kangoo 1.4 rxe has a strange problem. The heater fan is running flat out unless I disconnect the battery! The central speed switch has no effect and the fan runs even when the speed switch is disconnected. I have tried removing the fuses and relays within the cabin without luck.
Any ideas? It feels like a stuck relay but don't know if or where a relay feeding the heater blower is located. Help please.
Can't do any harm to wait a little longer - let me have an update when you can.
My earlier research did throw up this common fault but in every case the fan would either only run on the high speed setting or not at all. The situation we have is that the fan won't stop at all even with the ignition off. I cannot see how the blower motor is getting any power without the keys in position 1 at least. I am trying to source a wiring diagram to see how this might happen before I buy a replacement resistor. Please bear with me for now.
