I am currently driving a 2009 xc70 (3.2L model) and I am hearing water sloshing around in the dash on every abrupt turn. There is no visible interior or exterior leaking.

I thought it was the A/C drain from reading some forum posts about water noises, but I can't find the drain to unclog it if this is the case. Where is the A/C drain? Where is water accumulating in my dash ?

Thank you for the help.

 

The water is most likely in the air conditioning system and the drain is plugged.

I can't recall where the drain is exactly, but I think that it is in the RH firewall area toward the lower end. Typically there is a black rubber hose sticking out.

Put a shop vac on the end of the hose and you will probably clear the line that way which is the best practice.
