Controlpanel in driver´s door was old and the pins didn´t make any contact. I took the wire connectors off the controlpanel. I tought that other windows should work but they doesn´t. Sunroof works every other time. Where should I start. Metal fuses are ok, but where is the relays for these operations?

Hi and welcome to the forum.
The relay should be under the dash close to the hood release. Have you checked the ignition?

All 4 window controls go through the master door switch. You need to find a replacement switch. No window relays.
The sunroof is a different set of wires and not related.

Power runs from the battery, through main fuse 11A/2 to supply the load contacts
for "overload" relay 105. ( It shows in the wiring diagram as relay 2/30, but on the
component location page as relay #105 ).
The overload relays power up the switched fuses for many of the car's systems when the
ignition switch energizes. Their job is to reduce the load on the ignition switch contacts.
#105 also supplies power to the automatically resetting circuit breaker ( C37 ) that protects
both the power window system and sunroof. ( These are all the same for '98-'00's ).
What typically happens is that the master window switch develops a fault. If the fault is
serious enough to result in a short, not only do you have problems using the windows,
the auto circuit breaker overheats and trips - Then the sunroof doesn't work either.
The breaker will typically heat up and cool down in cycles, creating intermittent power
to the sunroof and window systems, consequently making it more fun to diagnose...
As Klaus mentioned, all of the windows depend on a good master switch to function.
In addition, except for the driver's window, the power windows also require a good
local switches to pass power and ground to the window motor for it to work, as well.
ALL of the window switches need to have good contacts for everything to work.
So - pull your master switch. ( And you can do that without pulling the door panel.
It pops straight up and out ). As long as it's unplugged, the circuit breaker should keep
cool and your sunroof will work. That will prove out the bad switch theory.
You can also take a look at this post and you may be able to rehab the switch:

It may also be a bad local switch in one of the doors,
but 9 times out of 10, it's a bad master switch.
And here's a better look at the circuit:
