Are you aware that the heater is actually designed for cooling an engine? It's built with a heat exchanger known as your Pontiac Trans Sport heater core. It's basically a small radiator. It functions to collect hot coolant from the engine into its tubes and uses the attached fins to magnify heat transfer to air from the fan. The heat your heater core generates is utilized to warm the interior.

The Pontiac Trans Sport heater core is located beneath the dashboard. First part you'll see is the fins that are attached to brass or aluminum tubes. Your heater core has an tubes that are for collecting and flowing out coolant. You can manage the warm air from this component via flipping your heater knob mounted on the dashboard of your vehicle.

Neglect, the tough functions, and time-incurred damage will eventually have effects on the heater core. You don't actually have to endure bad performance and/or upgrade the whole heater system to recover your Pontiac Trans Sport heater core performance.
