Turned on heater and got cold air. set it to 90 and the the temp guage got to half and only got a small amount of heat. vehicle started to have windows fog had to turn on A/C to clear them. It was working fine just two days ago last time used.

I'm only getting minimal heat. It's full of antifreeze, thermostat works fine & system holds pressure. It was ½ gal. low on antifreeze when serviced before winter. All the hoses are hot & the guage moves showing center between H & C after warming up.

Truck warms up you can feel heat when you put the fan on it gets cold
i had the same issue in my truck which is a super cab xlt WITHOUT dual climate controls. all of a sudden one chilly morning on the way to church, no heat at all. mine turned out to be the blend door actuator. dealer item in stock, cost me around $14, the part was cheap because they sell a ton of them. i changed it my self and it took me around 3 hours because i'm a carpenter not a mechanic
