Most likely to be a faulty resistor block, which has 3 resistors and a thermal fuse controlling fan speeds 1,2 and 3, maximum speed 4 by-passes the resister block. It may also be poor electrical connections to the resistor block caused by overheating. Renault ask for approximately £350 to carry out repairs, a replacement resistor block will cost £50. If you decide to carry out the repairs yourself, be advised that if you are not competent to carry out such work you, could cause electrical damage or worse an electrical fire.

put a new one in with sd card and usb facility and dump the renault one.please dont start me off with renault electrics again and their encrypted software.

Hi - the way to enable code mode is to turn off the radio - then hold down 2&5 & press the on button - this will bring you into the 0000 code mode.
