No Interior Lights

[danicroitor]

Hi, 

I don't know the reason, but the interior lights in my car doesn't work anymore.  And I mean, all the lights. I've checked all the fuses and they are all ok.

Can't figure out what's the problem.

Ideas?

Let me know if these are not for your year, I think they should be OK.

Have a look at the interior lights wiring section in the attached wiring diagram, pages 17-20. 

It looks like S157 could be responsible, find this in the other document, pages 9-10.  Also it looks like BOTH sides of the interior lights get switched by relays, and again these look like they are on or in this Multi-Function Control unit.

You can measure the voltage on P3/4 (read plug 3 pin 4) and P4/2 to work out what's going on.

S157 looks fine. I'm going now to find that relay and to check it out.

Thanks for helping me.

Man, this is complicated. Can't figure out witch of those relays are the one. And what is that "multi-function control unit"?

I think this is the relay, but I don't know how to locate it.

The MFU is the whole unit next to the fuses, it contains relays that are soldered onto a board, I don't think these are available separately so you need to be sure

The link below shows how to remove the MFU (level 1)

Oh, thanks. 

removing level - 1 already done that.

I have parts from another galaxy so I only have to figure out witch the relay is the problem.

 

Thanks for helping.
