Back in August 2023 the AC was blowing but not cold air. We scheduled an appointment and 2 days before we were going to take it in to the mechanic we saw a huge puddle of fluid under the car. It was just water. Took it in to the dealership and $4k later we had the car back. I don't have the paperwork with me right now to get all of the details of the repair noted for this post but basically they said there were metal shavings all through the front and back AC. Now the other day the air is pumping warm air again. Take it to the dealership and they say all of the repairs from August are good and that we needed refrigerant and they recommended replacing the service port valves so we had them do that. They also noted in the paperwork that they charged the AC and that the AC was running at 43 degrees. We picked up the car and driving home it wasn't working. Then it worked for a few minutes and not it isn't working again. I'm getting really frustrated with feeling like we are getting jerked around and not getting a thorough inspection. Thoughts/ideas?
