Problem with the air conditioning in my Renault Megane

A punctured evaporator can be costly to repair, as it often involves removing the dashboard to access the part. The cost can vary widely depending on labor rates and parts prices in your area, but it might range from $500 to $1,200. It's best to get a few quotes from local mechanics for a more accurate estimate. If you haven't already, consider checking for simpler issues like a blown fuse or low refrigerant levels before proceeding with more extensive repairs. Let me know if you have any further questions!
