Air conditioning problem
Why do I hear water swoshing when my a\c is on but not when not when it is off? Also when on I hear a strange noise when I turn left but not when ot is off. What is this ? Changed out blower motor and resistor.
Could be the normal sounds of a properly functioning R134a air conditioning system. If this is an abnormal sound then you may need to do some investigating in order to narrow down the problem.
but if you hear sloshing (especially on cornering) and finding that your carpets are wet, then check the plenum chamber where the drain holes get blocked on some cars.
