BUICK CENTURY HEATER PROBLEM

1999 Buick Century • 120,000 miles

A/c blows cold air, but heater blows cold air also. What could be the problem?

Check to see that both heater hoses are hot when engine warm if they are thenit's an actuator problem in heater. Or control. Check for a vacuum leak and check where i've pointed out in pic. They may not be working
