So my A/C in my car doesn't work the "econ" light is constantly on, meaning it's not generating cold air it's just recycling the air already in the car. Cooler weather is coming up and I'm wondering if it's okay to run the heat? Even with the heat on, the econ light is still on... I'm not sure if this is okay to do. With cold weather coming I don't feel like spending the money to fix the A/C right now...
