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 low side ac port to recharge on a 1999 ford exp.


To locate the low side line, follow the lines from the compressor. Typically, your low side line will be located on the left (as you face the front of the truck). It will have a small cap on it (similar to a valve stem cap on your tires). You may need to remove the air cleaner assembly for better access if the valve is in the back but in most cases, it's located nearer the front of the engine compartment, about 1' back from the radiator.

Where is the low side for the a/c on the ford expedition(1999)am trying to recharge my a/c.


The low pressure port is on the evaporator canaster on the Passenger side firewall behind the battery. Start the engine, turn on A/C, connect charge hose to port and pierce can of refrigerant and back the valve out to let refrigerant into the cooling system. It will probably take a few cans if it has rear A/C. Make sure you dont overpressurize the system, Use a guage with a safe zone meter to monitor the line pressure. Make sure the A/C clutch is kicking in or the system wont take the refrigerant. I hope this helps a little.

I can't find the low side fitting to recharge the system on my 99 expedition so did ford mean to make it hard to find so we have to take it to a body shop?


The port is on the oblong tank under the wiring junction. Just follow an a/c line you can see back towards the fire wall. There will be the customary black cap covering the fitting.

I need to find the service port for the a/c system on a 1999 Ford Expedition. The one up front and high will not allow the service quick-disconnect hose to connect.


do not try to fill through the high pressure port.

The low pressure port is on the side of the accumulator/drier. Please rate as solved if this is what you need.

Cannot find the lower freon input on 1999 expedition


They are coded blue and red. Low side, and High side. It's a plastic cap.

A word of WARNING! If you are attempting to recharge your AC, and do not know what you are doing, SERIOUS INJURY or DEATH can result! Connecting a recharging container to the RED HIGH SIDE can result in rupture/explosion of the cylinder.
