Ford Explorer 1991

I would like to know the possible problems that the retro lights, the 4x4 button and the steering wheel buttons and their possible solutions assume that the vehicle is recently acquired and its previous maintenance is unknown and its previous maintenance is unknown

First, the first thing Czech fuses, if all the lights that do not turn you have to do with the CMABIOS box check that the connectors are and that the box is the one that corresponds and does not disconnected it, all this is visual the other thing you can do is disassemble the board and check that the spurs are in good condition and not burned, to start,

Hi Brother Kiero Saver If there is Electrical System Manual of Ford Explorer 1991 4x4 by FIS I have problems with the start
