The right indicator bulb stopped working together with the Daylight bulb suddenly, right side indicator, but the mirror turn indicator is working, and the tail light indicator is also working,
I tried to remove the indicator bulb and put it on the left side indicator socket, both the daylight bulb and indicator are on and working properly and the left side indicator bulb does not work on the right side

Hi,

The only thing I see in common is the ground for both. Tell me; does the parking lamp work on the right side? If it doesn't, I need you to remove the bulbs and check the brown wires for continuity to ground. Here is a link that you may find helpful:

If the park light doesn't work either, the ground is the likely cause. It will be located behind the right kick panel. That would be where the passenger's right foot would lean against to the right.

Let me know what you find or if you need help in any way.

Take care,

Joe
