Hardware Faulty joycon or joycon rail?

[AutumnWolf]

My left joycon keeps disconnecting when I am playing in handheld mode, but the pins on both the joycon and the joycon rail seem fine to me.

The joycon does not feel loose either, it is perfectly attached to the console.

Should I have the rail replaced? Or does anyone know how to replace it?

Said joycon works perfectly via bluetooth.

Possible the ribbon cable connecting the rail is not seated properly or is dirty/corroded (on either the JoyCon or Switch side)

Maybe, I´ll take my Switch apart just to check

It turns out I don´t have a tiny enough screwdriver

You can check iFixit's guide for replacing the Joy-Con Rails.

Not saying it is the solution, just giving you the guide.

Also, did you try cleaning the pins with a brush or something, who knows, maybe it helps.

Thank you, I´ll be buying a tiny screwdriver in a few days
