The charging port is located on the firewall behind the engine. It is slightly off-center toward the left side of the car, so access is easier from the driver's side. With the hood raised, find where the passenger-side windshield wiper arm attaches to the car, then look directly below it on the firewall. You'll see a silver/aluminum tube coming up the wall and looping back down (this is the low-pressure side of the A/C system). At the top of the loop is a black cap that screws off/on covering the charging port. Turn COUNTER-CLOCKWISE to remove. It may be difficult to remove especially given it's location. Do not be tempted to use pliers (but if you do be very careful not to damage the port). Also, be very clean and do not allow any dirt on the port, the smallest dirt in the system is trouble.
Best of luck to you.

mcdevito75 here, The low side port of your A/C is located on one of the shiny metal lines comeing out of the firewall, they are attached to the evaporator under the dash, from the firewall carefully follow these silver lines till you reach the charge port. The port may be covered with a brass looking cap, un srew the capp and the port looks like the valve on the tire.

I'm wanting to put freon in my 1999dodge durango and I don't know which valve I put it in. The package said it would have a black cap and both ports have black caps.


you need to hook up the charging hose to the "low Pressure" port it should be the one closest to the a/c compressor, if you look at the lines coming off the compressor you will see it!!
it is the smaller one, the charging connector will only fit on one of the ports, so if it appears it will not slide on to the port then you need to try the other port!
also make sure the engine is running and the a/c is turned on while you are adding freon!!

How do i charge my air conditioning in my 1999 trail blazer


You do not wan to charge an A/C. By law you must first have the AC system checked for leaks before adding freon. If freon is released into the air you can be ticketed for up to $10,000 Once you have your A/C checked for leaks than repost the question and I will gladly assist you.

Trying to recharge air conditioning. need to know info.


Large line is the suction. When charging freon always use the larger of the two lines. If there is a charging port at the accumulator(canister shaped device on/near firewall), use that one. Inside the accumulator is liquid. Good luck.
