I need to know where the recharge port is to recharge A/C on a 1999 Ford Expedition


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.

Where is the A/C recharge port located in a 2001 Buick Regal?


Find your A/C compressor. On the compressor you will see two pressure lines, one small and one larger line.
Pick the larger line and follow it back to the firewall, on that line will be your "low side" charge port for recharging purposes.
Good luck, let me know.

AC has stopped blowing cold air. Compressor is working. Where is the recharge valve located?


There are two A/C refrigerant lines. The small line is your high pressure line and the larger line is your low pressure line.
Start at the fire wall and follow the "large " low pressure line to the compressor. The low pressure charge port will be some where on that line.
DO NOT try to recharge on the high pressure side ( small line )
Good luck, let me know.
