the weather in ohio is cold and started to snow and my heater barley works, when the switch is turned on it blows out cold are even when set to defrost the windsheild. another thing is when i have the switch off i get warm air coming out of the vents, i have no idea where the heat is coming from and am wondering if it is heat coming off of the engine, if this makes any sense please help me out

 

Sounds like you have a problem with your blend doors. It switches the door to open to the heater core or the AC system. The switch is cable operated. Check to see if that is your problem.

 

forgot to metion that the ac dosnt blow out cold air, what i mean is its the temp of the air outside. so in the summer the air is hot and the winter it is cold. and where is the switch located ill check it soon

 

The switch is the one you switch from hot to cold.

 

oh ok, how would i go about checking it and how do i know if its wrong and i take it ill have to remove some of the center console
