I almost always use the auto setting for the A/C and heat in my vehicles. I have noticed since the weather has turned cold that when I turn on my Ram the heat blows cold air immediately and does not wait for the engine to warm up. Every other vehicle I have owned has waited until the engine is warm enough to blow warm air before it starts (thus, auto heat). Is anybody else having this issue? Is it just a Ram thing and it just blows cold air until the engine is warm and adjusts the cabin temp until it is set? Seems odd to me that it would blow cold air and not wait until the engine is warm.
