Peugeot 306 no lights or heater motor
My sons P reg Peugeot 306 Diesel had no main beam, sidelights, rear lights dash illumination and and the heater motor was not working. Fuse
7 under the dash had been replaced and a so called expert quoted =A3400 to replace the wiring loom that runs under the radiator.The cause of the problem turned out to be dry joints (poor soldered connections) on the Printed Circuit board inside the fuse box under the steering wheel.
Remove all 10 plug/socket connectors to the fuse box (they are colour coded blue, green, red, yellow, brown, black, white, grey, brown and orange.
Remove the fuse box assembly and prise open the clips to reveal the printed circuit board. Examine all the soldered connections for arced/poor connections and re-solder.
Re-assemble and plug in the 10 plugs.
This cured the problem and all lights and heater work fine.
