I have a Ford Scorpio Cosworth Limusine Bj.10.86 in which the complete interior lighting has failed. The fuse (no. 24 with 10 A radio, interior lighting) is fine. The relay I have swapped with the rear window for trial (equivalent to the rear window) and it is also fine. There is supposed to be a wire diode in the cable, which is probably defective. And now the question: Where could the seats ?.
