None. All cars produced after 1994 use r134a in their a/c systems instead of r-12 (freon). Your car should have a sticker under the hood somewhere that details the amount of refrigerant in the system, although when you charge an ac system you are not measuring the amount of refrigerant, but rather the pressure. You can get a can of r134a and a reusable charging manifold at a car parts store for about 20 dollars to fill your a/c system up to the correct pressure. It may take anywhere from half a can to a few cans depending on how low on refrigerant your system is.

To add Freon to a 2000 Mercury Grand Marquis, locate the low-pressure service port on the AC system, which is typically found near the accumulator or the firewall. Remove the cap from the service port, attach the refrigerant gauge and hose, and then add the appropriate type of refrigerant. Be sure to check the system pressure with the gauge to avoid overcharging. Always follow safety precautions and consult the vehicle's manual for specific instructions.

Why does my heat work but ac don't on a mercury grand marquis?

The heater and the AC are different systems other than the blower, so they normally fail independently. The AC can fail for many reasons, high on the list are low freon (which means there's a leak) and the compressor.


Where do you put in freon in a 1998 grand marquis?

First, your 1998 Mercury contains no Freon which is R12. It contains R-134 refrigerant. You add R134 at the low pressure port. But the fact that you need to add R134 indicates you have a leak. It is illegal to add refrigerant to a system with a leak without first repairing the leak. Seek professional help and have the leak repaired.
