Well, the washer remedy won't work in my case. A simple test could be made by pressing hard on the switch button. If lights turn off, then one could say it just need tighter press on the body. The magnet or the washer remedy would apply.

I just tested the wires on the switches today, i found out that power supply on one of the wires fluctuates or fades away. Loose wires could be causing it or a relay switch could be malfunctioning. There may be a need to check wiring connections under the dash. I need more time.

I temporarily disconnected the door open sensor of the car alarm so i could switch the alarm on for security and be able the remote auto door locks. Ceiling lights are also switched off, the car still alarms if door is opened not by the remote control.
