2004 Volkswagen Golf

I used this vehicle to go to school, I got a newer car. I dont need this anymore. Its a great car with fair mileage, very comfortable to drive. It has new tires. I always took good care of the motor, complete tune up a year ago, along with new catalytic and fuse box, oil changes always on time. New spare tire. Timing belt and water pump replaced back in 2017-2018. I’ve noticed that the A/C is not blowing cool air, It might need to be refilled. The air sensor was replaced last
