You can run a self-test on the ACC. The result isn't always correct, but it's a start.
Lack of heat can come from a lot of things, and many shops will simply "replace the computer", because it's easy. And most of the time it isn't the computer. If they can assure you that the heater flap is working properly, that the servo to heater flap linkage is OK, and that the servo is operating properly, and that the cabin air temp sensor is OK, and that the problem is indeed that the ACC doesn't drive the heater flap servo to the proper position, then, and only then, assume it's the ACC box itself.
