Is there a fuse or cut off valve for heater on a 2001 dodge stratus SE coupe the heater blows cold air like the air is on?

The 2001 Dodge Stratus SE coupe does not have a specific fuse or cutoff valve for the heater itself. If the heater is blowing cold air, it could be due to low coolant levels, a stuck thermostat, or issues with the heater core. Checking the coolant level and ensuring there are no leaks is a good start; if those are fine, the thermostat or heater core may need inspection or replacement.
