Do you guys have this experience that the light on the gearbox doesn't go off even when you switch off the engine ?

Anyone else having issue with the Aircon ?
My 2015 Mazda 2 has been experiencing aircon issue since the start of the month.
I’ve changed
1. Condenser
2. Cooling coil, block expansion valve
3. O ring inside the compressor

And it’s still having issue of not having consistent cold air.

Really disappointed with this version of Mazda.

Family owns a 10+ years old Mazda 6 fully import from Japan and it still runs perfectly fine until today.

There’s leak everywhere but foreman told me it will be stopped after changing o ring inside compressor. Now it’s the valve blocking cold air to enter the vehicle, which doesn’t make sense at all because I just replaced it.
