Re: 1999 FORD TAURUS EVAP SERVICE PORT
The AC charge port is the on low pressure AC line (large line from compressor) near the firewall. Take care not to overcharge, there are other causes of no cooling like a stuck AC compressor cycling switch or a air temp control blend door motor malfunction, what is the issue u have? does the AC compressor run?
a 6ya Mechanic can help you resolve that issue over the phone in a minute or two.

Hi, the low pressure port is along the line that goes from the firewall to the compressor. It may be on the dryer, if there is a dryer on that line. The port usually has a black cap screwed onto it. I will look for a picture. Do you have the 3.0 engine?
Your A/C system will have two service ports, there isn't any "recharge" ports. You add refrigerant to the LOW side only. Prior to adding any refrigerant, you need to check the system pressures with a manifold gauge set. If the system has enough charge and there is another issue, adding refrigerant can make for worse problems. Automotive A/C is best left to the right person with the proper equipment to service them. If you follow the lines from the compressor, the LOW side will be the smaller diameter of the two service ports.
The low side port is located near the firewall at the back of the engine compartment near the right strut tower. It has a black plastic cover similar to a tire valve. Do not connect to the high pressure side which on my vehicle is located towards the front of the right side near the radiator. You will need R-134a and a connector kit. If you have leaks they should be corrected before recharging.Thanks. Keep updated for any more query. You can rate this

mcdevito75 here, I have a 96" and yes you can charge the A/C yourself and you can use the 134A, the Charge port is on 1 of the metal lines comming out the firewall mine is on the metal line just about 6--7 inches from the firewall, the kit you buy for recharge will only fit this low side port, also follow the cans directions very carefully. there may be a screw down cap on this port simply unscrew this cap, port will look similar to the air valve on your tires.
go to auto zone and buy a 134 recharge kit follow the directions on the box, you will need to find to LOW side service port there are two ports with plastic caps on the ac lines you are looking for the one that is attached to a larger diameter ac line. the kit will ONLY FIT ON THIS FITTING so you dont have to worry, there is a label under the hood somewhere thats green and says how much 134a you should install be carefull wear safety googles and good luck, please rate -jeff
