Technical New Ulysse with elektronical probs

[Monster900]

Few weeks ago I bought a 2003 Ulysse. I'm very happy with it, but it has a few small problems. This morning I fixed a dodgy rear-screen wiper, and now I'm searching to fix some background lights...

The radio/phone/sat nav/EOBD-display is unreadable at night, unless I use a flashlight. I took the display out, but I've seen the lights are 8 or 10 LED's. I don't think all 8 LED's failed all at one, so I think there is a problem with some wires...

Don't want to damage anything with a testlight testing all cables. I'm afraid those cables need a specified resistance, and if I just use a testlight or anything, I will damage it.
Is there any elektrical scheme to find on the internet??

Thanx already for any advice!!!

No-one who can give me some help????

Yesterday I also noticed CruiseControl isn't working anymore. Checked Fuses, but they're all fine! :S

Cruise Control now works fine again, without having anything fixed.
BUT!!! Last Wednesday, I went shopping. Opened and closed the car several times with the remote, to put some things I've bought in the trunk. When I wanted to leave after visiting 5 stores (so opening/closing Car 5 times) the central locking failed...
Now the doors won't close or open with central locking. Anti-carjack-sysytem doesn't work, can't open trunk, etc. etc.
I tried to find any faults with an OBD-computer. I was able to lock and unlock the car with the computer, but buttons on remote or on the roof didn't work.
Although I'm able to activate automated locking with the button, and the buttons for electrically opening doors make the beeper work, when activated while driving...
That means the buttons still work, but they don't have the effect I want.

Anyone who can help me with a workshop manual or electrical scheme?

Have you checked for water in the fuse box, also disconnect battery for about an hour and then connect again, this fixed a lot of my problems!T

I've disconnected the battery, held -cable to + to discharge condensators, and reconnected. Central locking works fine now Thanx for the tip!!

Except the right sliding-door doesn't open or close electrically, only with human force... Any tips?

Sliding door works, but I don't have a clue what I did to fix it...
