Add Freon to 95 Taurus SE

HI

I have a 95 Taurus SE 3.0. My Compressor is working, it is blowing AIR but not cold. I went to Auto Zone and bought a can of R134 gas to fill in. It says in the can that there will be two pressure ports high and low. I don't know which one is what and I only see one on the Left front near the washer fluid.
Kindly tell me which one to use and where to find the other port if there is any in 95 Taurus.

I also hear a clicking sound when i turn the Ac on. I don't know what it means. Tell me if you know about it.

Thank you

I just had to do that for my 94 GL Taurus a few days ago. I believe your car is the same style as mine. You want to connect your can of r-134a to the LOW SIDE of the A/C system. Ford sets you up showing that valve near the front of the car by the washer fluid. DO NOT ATTACH YOUR CANS THERE that's the HIGH PRESSURE side and you can blow up the can or damage your A/C system!!! Instead, Ford hid the LOW SIDE terminal under the plastic covering near the windshield. Follow your hoses that run along the sides of the washer fluid and coolant reservoir all the way back to the firewall (into a cylindrical container called the evaporator). You'll notice a plastic covering that runs along the back where the hood meets the windshield just above the evaporator. Remove the screw holding the plastic covering nearest the AC lines (the left most screw when looking into the engine compartment standing in front of the car). Pry it back to reveal the LOW TERMINAL SIDE of the A/C (should be near a gold sticker that says r-134 a wrapped around the hose). Remove the plastic cap and you should be in business. You may want to buy a can of A/C lubricant and sealer along with 1 to 3 cans of freon. I also had to hold my cans upside down to let the freon drain into the system, cans become cold when they are draining, then just wait until they warm up, that indicates they are empty. Better to pay $30 to recharge the system on your own than pay the dealer $300 for the same thing.

The clicking is normal, indicates your compressor is turning on and off.
