    Does anyone know what this drain tube does?

    It's located on the right rear passenger side coming from behind the headliner and running down the C pillar, connecting to a tube that seams to run on the floor towards the dash, then goes back up into the fire wall.

    I'm installing a new OEM HV battery and noticed this line is full of water. I got some weed Wacker trimmer wire and tried to unclog it but ran an easy 10' of string down the tube before it stops. I cannot unclog it.

    A bit weird it doesn't drain at the bottom of the car?

    I believe what you have there is the rear window washer supply line.
