Where is the low side port to recharge air conditioner on a 1998 Chevrolet?

On a 1998 Chevrolet, the low-side refrigerant port for AC recharge is typically located on the dryer/accumulator. This is usually a cylindrical canister near the firewall, often on the passenger side of the engine compartment. The low-side port is usually smaller than the high-side port and will have a blue cap (though sometimes these caps can be missing or replaced, so look for the smaller of the two ports on the drier/accumulator).

However, the exact location can vary slightly depending on the specific model of your 1998 Chevrolet. Consult your owner's manual or a repair manual specific to your year, make, and model for the precise location. A diagram would be incredibly helpful.

Important Note: Recharging an AC system can be tricky and requires specific tools and knowledge. Improperly recharging it can damage the system. If you're not comfortable doing this yourself, it's highly recommended to take your vehicle to a qualified mechanic or AC specialist.
