Recharge the air conditioner


Instructions
    • 1Start the recharging process with any left over freon you may still have. Open the Civic's hood and attach the kit to the Civic's low side port. Then, set the kit onto a place in the engine compartment where nothing can move or shift once the engine has been cranked.
    • 2Start the Civic and let the engine run until it reaches its normal operational temperature.

      • Single Pressure Gauges for Indl., Commercial & Specialty Uses

    • 3Turn on the air conditioning to its coldest and hardest-blowing settings. Place a thermometer into one of the Civic's air conditioning vents and monitor how the temperature drops. Once the air conditioning's temperature reaches a level, constant degree, remove the thermometer.
    • 4Open all four doors on the Civic. This will allow any colder air generated to escape, and this will keep the Civic's air conditioning for accidentally cycling off while you recharge the refrigerant levels.
    • 5Turn the recharging kit's valve all the way down and let the refrigerant charge into the Civic's air conditioning periodically, shut the valve and look at the kit's gauge. This will allow you to monitor the recharging process. Allow at least one minute to elapse between refrigerant charges into the system.
    • 6Shut the valve of the canister, once it has become depleted. Disconnect the kit from the low side port.
    • 7Detach the hose, gauge, and valve from the empty canister and attach them to a new canister of refrigerant. Reattach the kit's hose to the Civic's low side port and continue recharging the system, allowing a minute between individual charges. The can itself can potentially grow very cold and hard to hold, even with gloves. Should this happen, wrap the can in a towel warmed in water. Ring out excess water before wrapping the canister.
    • 8Place you thermometer into one of the Civic's air conditioning ducts. Keep an eye on the falling temperature within the Civic's air conditioning system. The system is charged when the temperature hits 40 degrees. Also, within the engine compartment, the Civic's air conditioning aluminum tubing become uniformly cold.
    • 9Shut the recharging kit's valve and remove the kit from the low side port, once the system has been successfully recharged. Shut down the Civic's air conditioning, turn the engine off, and remove your key from the Civic's ignition. Also, shut all the doors

Air condition don´t start, a honda civic


Air conditioning systems sometimes leak down and won't turn on when the refrigerant levels are too low.

Lift the hood and listen to the A/C compressor while someone inside the car turns it on.

Does the compressor engage for a second or two and then shut off?
If it does....you need to have your system checked for leaks and recharged.

If the compressor never comes on. Look at the A/C compressor relay. It should be under the hood in a little fuse box with other relays and fuses. When you find this relay you need to see if it works. You can buy a replacement relay and swap it or take it to a parts store and have it checked. Relays are 10-30 dollars and you should have three or four relays of the same type so a real cheap test is to swap a identical relay from an electric window or a defroster. You should see them sitting right next to the A/C relay if you have them.

Good luck and be careful!

Where do you recharge the airconditioning unit on a 98 jeep grand cherokee 4x4 loredo? Need the location of the fill valve. I already have the recharging kit.


Jeep GrandCherokee SUVs manufactured in or before 1995 use R12 refrigerant. You must retrofit these SUVs to accept R134 refrigerant using a retrofit kit available at your local auto parts store before you can recharge the system. In some areas, a license is required to retrofit an air conditioning system. If this is the case in your area, take your Jeep to a professional to retrofit the system.

Instructions:
  1. Step 1 Take your SUV to a mechanic to recover the R12 refrigerant out of the air conditioning system. A license and special equipment are needed to do this. Because R12 refrigerant is expensive, many mechanics will do the job for free.
  2. Step 2 Locate the Low Pressure Side connector port. You will find it on the driver's side of the engine. Remove the blue or yellow cap marked L. You only need to retrofit the system if you see a screw-type connector valve. If you see a quick connect valve, the system already is R134 compatible. Wipe the connector valve off with a clean towel. This ensures that the retrofit connector properly adheres to the valve.
  3. Step 3 Place the long retrofit connector from the automotive retrofit kit onto the Low Pressure Side valve. The retrofit connector has a special adhesive on the threads that will help it adhere to the valve. Screw the connector onto the valve. Tighten the retrofit connector using an adjustable wrench. Place the cap provided in the retrofit kit onto the retrofit connector. This keeps dust out of the system.
  4. Step 4 Follow the air conditioning lines away from the compressor until you see the High Pressure Side port valve. This is located near the Low Pressure Side service port. Remove the red cap and wipe the port off with a towel.
  5. Step 5 Put the shorter adapter onto the port. Twist it using an adjustable wrench until it is securely fastened to the port. Place the red cap from the retrofit kit onto the adaptor.
  6. Step 6 Fill out the Retrofit Identification sticker provided in the retrofit kit using a permanent marker. Remove the protective backing and place it on the interior side of the hood. This lets future owners and service professionals know that the system has been retrofitted.
  7. Step 7 Recharge the air conditioning system. See the related eHow titled "How to Recharge Air Conditioning with Freon in a Jeep Grand Cherokee."
WARINING:
Never try to evacuate the system yourself. A license and special equipment is needed to evacuate the system. Attempting to do this yourself will release refrigerant into the air, which is a federal crime.

Good luck (rated this help).

Where's the low A/C recharge valve in 1995 GMC Suburban?


The valve will be under your hood, on a line that runs from your AC pump, and it will have a blue cap on it. It's about three times as big as a tire valve cap. It sounds like you should let someone else do it.

AC is not working


Sounds like the A/C system just needs to be recharged. When was the last time you had this done? Just take it in to your mechanic and he can do it for you and if that's not it for some reason, then he will be able to find the problem but most likely you need more freon added.

Air conditioning needs recharged


First, you have to locate the thicker line in the compressor, then follow up until you find the valve to recharge the system, usually is located near by the accumulator bottle.
