What causes an AC accumulator to stop working?
There are no moving parts in an AC accumulator. But once an automotive AC system fails, debris and moisture can deposit in the accumulator. Also, if the AC system is open to the atmosphere due to a broken hose or leaking evaporator or condenser, the desiccant bag in the accumulator can soak up too much moisture, rendering it useless.
Where is the accumulator located in an AC system?
