Where is the AC recharge port on a 1999 Chevy blazer?

The AC recharge port on a 1999 Chevy Blazer is typically located low on the engine compartment, near the compressor. However, it's not always in the exact same spot across all models. It might be on the compressor itself, or on a nearby line. The port is usually a low-side service port and will be a Schrader valve (looks like a tire valve). It's often capped.

To find it definitively:

* Consult your owner's manual: This is the best resource. It should have a diagram showing the location of all service ports, including the AC recharge port.

* Use a shop manual or online repair guides: These often have detailed diagrams of the engine bay. Search for "1999 Chevy Blazer AC recharge port location" along with your specific engine size (e.g., 4.3L V6) for better results.

* Look for a low-side service port: As mentioned, it will be a Schrader valve often capped, usually near the AC compressor and lines.

Caution: Working with refrigerant requires specialized tools and knowledge. Improper handling of refrigerant can be dangerous. If you're not experienced with AC system service, it's best to have a qualified mechanic recharge your AC system.
