i have a problem with my AC/heater system. when i run it, i can hear the vents constantly clicking open and closed, and also i hear what sounds like coolant sloshing around behind the center vents. anyone know what this could be?

i figured out the problem, i think. i changed my coolant last week, then used my heater for the first time the other evening. i think that sound was the coolant filling up the heater core (?). i think the noise has gone away.
