On my '93, there is no consumer serviceable port. I think the recharge has to be done by a technician.
I have a 2003 Grand Prix GT and the AC recharge port is right behind the motor on the firewall. Look for the silver pipes coming out of the firewall right near the middle. You will see the recharge port on one of the pipes there.
On a 1993 Mercury Grand Marquis ( which is OBD I , EEC IV ) ( there should be an EEC TEST connection in the engine compartrment )
The 1996 Mercury Grand Marquis OBD 2 port is on under driver side dash next to center console
Under the dash on the drivers side.
I believe the obd port is located by the parking brake and just above it.
Looking at the engine from the front, look on the left side. You should see the evaporator sticking out of the firewall. There is a round tall thing in front of that with a hose that runs to the front of the car. It sticks out of that black tall thing on the hose.
where is the ac recharge port on a 93 ford explorer located?
On the low side service port that is located on the a/c compressor manifold.....
left side on firewall should be on the side of ac condencer
Look under car...look for blue c as p near compressor...
The Freon recharge port can be found on the top of the air conditioner compressor. There will be two ports. The recharge port will be labeled as the low pressure port.
Black capped port on the front left (as you face the car with the hood up) of the engine compartment. It's right by the radiator in my 3.4L SE1.
