heat trouble shooting from @ A/O

Flush cooling system would be my first step. This is something we overlook way too often. Running the AC shouldn't allow you windows to fog. When you run your defroster in runs the AC to dry the air so you are blowing dry air on your windows to keep them from fogging up. so that part doesn't make sense to me. But definately start with a coolant flush. Has the truck ever had one? doing this every few years is a great thing. Another thing is to check if the blend door is working. Not the door that changes the [ath of the air flow but the blend door that "blends" the cool and hot air. These had a tendency to go bad on dodges.

these are just my opinions and should be taken with a grain of salt.
