Where is the low pressure port located on a 2000 Chevy blazer?

The low pressure port on a 2000 Chevy Blazer's A/C system is typically located on the accumulator/receiver drier. This is often a cylindrical component near the front of the vehicle, sometimes close to the firewall. It's usually a smaller fitting than the high-pressure port.

However, the exact location can vary slightly depending on the specific model and engine of your 2000 Chevy Blazer. It's best to:

1. Consult your owner's manual: It may have a diagram showing the A/C system components.

2. Look for a diagram online: Searching for "2000 Chevy Blazer A/C system diagram" should provide visuals.

3. Use a repair manual: A Haynes or Chilton repair manual specific to your Blazer year and model will be the most definitive resource.

Important Safety Note: Working with refrigerant requires specialized tools and knowledge. Improper handling can lead to injury or damage to the A/C system. If you're not comfortable working on your A/C system, it's best to take your vehicle to a qualified mechanic.
