Start at the combo switch my friend.

perhaps one step even more basic. Check the fuses.

I bought new fuses and it burns them . Any other ideas ?

It burns them as soon as I replace them ):

Then you have a short circuit that has connected one of the items on the circuit powered by that fuse (fuses?) to ground.

Start by looking at each of the bulb sockets on the circuits that don't work. Corrosion is the likely culprit. Marker lights are the usual culprits. Also check the glove box light wiring. For some reason many had that wire fall off and come in contact with the chassis causing problems. Then start checking each connector in the wiring harness starting with the ones under the passenger side dash.

Also - you can get an electronic version of the Factory Service Manual over at Ratsun.net.  Get one and trace the electrical circuits that those lights are on so that you know everything that is in each circuit.
