check the connection to the alternator, it may just be loose. if not then diode inside may be broken

Loose wires to the headlights or fuse panel.

Considering all the things you've replaced, It's time to look for a possible bad light switch or bad connection to it.

Hi J, The ground connections are on each of the units. that is to say there is one power feed to the dome and another to the instrument panel. From there each door is separately grounded via each of the door switches. If one is rusted, contaminated or damaged and not operating correctly, it will cause the dome light and the door warning on the instrument panel to flicker. regards John

by the explanation that you have submitted,the circuit board behind the instrument cluster might be inching it's way to being defective.

bad ground at battery or chase.

Alternator, or wiring from alternator.

Battery failed.Or alternator problem.Recharge the battery then try..If red light is sill on when car is running then the alternator needs replacing

Further test showed that the interior (dome) and exterior light flickered only while driving. The problem was that the battery rack is broken. The battery negative terminal connect to the motor (OK) but also to the frame of the car through the battery rack. Since that rack is broken, the grounding of the car was intermittent. Whenever I shifted, it made the motor move in relation to the frame of the car, so that's why is caused all the light to turn on in the dash.
