My 1999 Volvo S80 T6, sometimes starts blower on its own. I have at few times returned to the car after a short park to find the blower running without the ignition on. I am worried, one of these days i might return to a dead battery. Pleas help!! Thank you.
If you are talking about the thermo electric cooling fan, its operation is independent of the car's electical system. It is switched on and off by the engine temperature. When you park, the engine heat soaks upward to heat the thermostat turning the fan on. It will run until the engine cools down and the thermostat switches it off.
Testimonial: "My minds at ease now. :) Thank you."
