Please help.

My car doesn't show the light on the cluster when the doors are open... When I'm sitting on the seat, it doesn't show the light of the seat belt. Also, the I don't have the warning buzzar that the head lamps are on, either the light signal doesn't come up o the cluster... I change the interior fuse box that somebody told me that is part of the multiplex box, but nothing.. Does any body knows about this problems.?? Thanks

 

Several problems are likely but related problem is possible.

You need a shop manual (wiring diagrams), and a test light to test electrical circuits. check automanualsource.com for $22 manual.

I enclose wiring diagram for interior lights. Looks like fault could be fuse, wiring, connector or bulb. Use test light to trace for 12V supply to ID faulty component.

good luck
