Maintenance/Repairs

I own a 1999 GMC Safari van. Within 6-months,mechanics replaced radiator & hoses, thermostat, heater core flush, water pump, heater core, heater core vales & assembly, radiator cap, vacuum checks and radiator flush.

The heater still blows luke warm air when I come to a stop sign and never heats the air like it used to. What is my problem?
