Heater problem
2002 Dodge Caravan 68000 miles

My heater does not work. It stopped working and the check engine light came on with the error code shown above. Do I need to to take it to the dealer to get fixed or can I fix this myself ?

The heater and P0601 are totally separate problems. P0601 means that there is something wrong with your PCM. A lot of times, re-flash works, but there have been instances that PCM replacement are required, in which re-flash is still necessary so the new PCM works with your vehicle.
