Here's how to generally find it:
1. Locate the glove box: The evaporator is typically behind the glove box.
2. Remove the glove box: You'll need to remove the glove box to access the evaporator.
3. Look for the AC lines: The evaporator is connected to the AC lines, which are usually silver or copper.
4. Identify the evaporator: The evaporator is a rectangular or cylindrical unit with fins.
Important Note: Working on your AC system can be complicated and involve refrigerants that can be harmful if not handled properly. It's recommended to have a qualified mechanic diagnose and repair your AC system.
Here are some additional things to keep in mind:
* Exact location may vary: While the evaporator is generally behind the glove box, its exact location can vary slightly depending on the specific model year and trim level of your Regal.
* Safety precautions: Be careful when working around the AC system as it uses high pressure and refrigerant.
* Professional help: It is highly recommended to have a professional mechanic inspect and repair any AC issues.
