Look really clearly at your fuse block under the dash there, those things have a nasty habit of rusting, and affecting the wiring to the spring loaded fuse holders....then there is the ignition switch itself....

you can pull the inside fuse block off with just 3 bolts, one to the bulkhead connector...either 5/16 or 3/8 nut driver....and then the 2 5/16 bolt heads on the inside.... that should enable enough room to investigate any burnt/bad/rust wiring

Check the fusible link at the bulkhead connector (engine side).

pfffffffffffffff ok ok

about power windows,

I found this, is that the small module on the drawing (29 300) could be the cause?

Not referring to the little glass fuses. I'm talking about a wire that is designed to burn in 2 to protect a circuit like a glass fuse. Your 76 has around 6 fusible links. Here is a thread where some fusible link chatter went on. Great reading.

The links in this pic are the orange and the larger black wire on the left in the pic. The large cylinder black plastic thingys are just connectors. The actual links are the wire.

This shows an orange fusible link, its the loop.

This is a link at the starter. Its the brown wire between the round black plastic connectors. This is from Duke94s car.
