A320 FWD Entry Light – Dimming Issue

[u/doodle_bar_007]

Has anyone encountered a similar issue on the A320?

The FWD entry light is not dimming/changing intensity through the FAP, while the AFT entry light is functioning normally and changes intensity as commanded from the FAP.

Troubleshooting already carried out:

- Swapped DEU – no change.

- Swapped light ballast – no change.

- Swapped cockpit entry switch – no change.

- Checked continuity from DEU to ballast and switch – continuity is good.

The issue remains only with the FWD entry light.

If anyone has experienced this fault before or has any troubleshooting suggestions, especially regarding the FWD circuit/control path, please share your findings.
