NIssan Altima 2002 model doesn't blow out Heat in Idle mode on 2002 Nissan Altima

When warming up the car, it never seems to blow that hot air, no matter how long it is running. The windows also freeze up on the inside. The temperature gauge on the dash seams to be moving as expected. When driving the car, the air does get hot in a reasonable amount of time. Even when Hot, if I get stuck in stop and go traffic, the air starts blowing cooler, until I get up to speed again
