My Renault Megane Scenic S reg heater is not working
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.
