Question about 2001 Chevrolet Blazer
Check the heater control valve (usually on one or both heater hoses just ahead of where they enter the firewall) make sure that the vacuum hose going to it is connected and that the actuator arm moves when you switch between ac and heat. Also make sure coolant is full and that engine comes up to operating temp.Under the dash, on the heater box there is a vacuum servo that operates an internal door. Make sure this is operating as well (same as htr valve) Likely one of these is your problem.
