I have a 2005 Nissan Frontier. The drive belt started squealing, and since have had it replaced 3 times. Each time, the belt is quiet for a short period of time and now again it is squealing. Any thoughts?

Also, the heat blows hot when the truck is moving, but blows cold when stopped or idling. I have removed the radiator cap and left run to remove air bubbles, the antifreeze levels are fine. Any thought on this, too?

Nissan has a bulletin on the belt issue. The belt and tensioner get replaced, and the power steering pump bracket gets adjusted. You have an air pocket in the heater core, needs to be bled out

I agree, belt tensioner issue will cause this problem, try parking the car on a slight incline so the radiator is at the highest point, run the engine with the cap off, any trapped air should make its way out to the highest point, this method can often clear stubborn air pockets.
