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 can i find the connection to refill the ac?


A/C system has a high and low side line. The line you add freon too is the low side. The lines are on the passenger side of the truck under the hood. The larger line is the low side line, follow it from the radiator back toward the fire wall. You will come across a fitting which should have a cap on it, but it may be missing the cap. Thats the low side port.

Today while I was driving, The instrument where it telles you how many miles left till empty read 27mi. all of a sudden it started counting down rapidly, within seconds it had went from 27 mi to 4mi left...


Sounds like float in fuel tank is sticking. Usually caused by using cheap gas. Fill it up and add a bottle of STP gas treatment. It might take more then one tankful w/STP to clean it completely. TIP: don't rely on the computer generated "mileage left" especially when that low on fuel, that is only an estimate. And also don't let it get that low on a regular basis because it will damage your fuel pump, fuel is used to cool electric pump in fuel tank and running it that low will shorten the life of your fuel pump.

What kind of refrigerant does a 1997 ford expedition use, I was going to use a r134 contection but it is to small to fit on my conection. When I look up what refrigerant to use in my 1997 ford expedition...


Your vehicle does use R134a. You need a quick connect hose that does only fit the low side fitting. The high side fitting is larger, you can not attach it to the wrong one, it will not fit.

Where is fitting for A/C recharge


I just recharged my 99 Expedition 4.6 L today.
Open hood and stand facing engine, look to left and 1st see the WW washer fill then the battery then at a 45 degree angle look to the firewall where you see a black cover just below the red and black battery cables going in and out of the solenoid. Underneath and behind is the Accumulator. On the side of this silver canister there is a hose coming out of the Accumulator and just to the right of it is a black cap over the Low side 13MM AC fitting. The cap does unscrew but the fitting takes a quick disconnect coupler fitting.
I found it helpful to search a parts outlet on the web and print a picture of an Accumulator for the Expedition. I was able to accomplish recharge with everything in place but next time it is likely I'll unscrew the two fasteners holding the wire assembly to the fire wall and move out of the way.
Best Wishes.

Where can I find a diagram for the low pressure ac port for a 1999 ford expedition


There are 2 hoses that come off of condensor in front of radiator. 1 is high side, has large cap on top goes to a/c compressor. The other is low side it, it goes toward firewall into or on the receiver dryer (looks like big can) You will find the charge fitting there. It is a smaller fitting usually blue or black cap on it.

Where is the low pressure ac port on an 1999 ford expedition 5.4l


If you find the big round silver thing (reciever/dryer) it is in it or in the same line nearby. Probably area of passenger side close to firewall. The low pressure side is the larger of the tubes.

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.
