So my 1990 LS gets no power on the interior lights,I have to press shift lock to move transmission to preferred gear, headlights are out, tailights are out, sunroof doesn't work any more and neither do the windows. The engine runs fine. This all happened at once.Also other symptoms are my dash lights go crazy when I accelerate hard at times but no so much anymore, my dash lights DO work and no CEL and my headlights just gradually started going out first I had no yellow fogs then the complete headlight bulb went out. I've replaced my battery, the ECU, and some main fuses but nothing.I am thinking it's the ignition switch. Can anyone help PLEASE.

Sounds like the 120 amp fuse. Have you done any engine work recently? Electrical problems are the worst.

That fuse usually takes out ALL the electronics when it blows but you can still start and drive the car but without power steering.

Fusible link corrosion at the terminals, all connections are suspect.
