Why will the heater only blow warm hot when driving at about 40 mph or greater on a 2004 Nissan Altima?

Coolant low in the radiator, or the vent down sills are plugged with leaves, and other debris.

The thermostat on the Nissan Altima should be directly behind the alternator. This will be on the passenger side of the car and directly under a large heater hose.
