You really should take it to a qualified shop for that. Do you have the tools to do a job like that? If you feel the need to do it yourself get back with me and I'll give you step bt step. OK

    There is a fuse for the compressor but there is also a low pressure cut off switch that will not allow the compressor to come on if the freon charge is to low. Do you know where your reciever/dryer (accumulator) is located? There should be a switch mounted on it. Unplug the harness (it should have 2 terminals) Turn the key on jump out the 2 terminals and listen for the compressor clutch to click on. If it comes on you need a recharge.

SOURCE: Would like to recharge my air conditioning on my 2001 nissian maxima that has 117,000 on it blows hot air when air conditioning is turned on.

You will need R134a, and a filler hose. Charge the system on the low pressure side, it should have a blue cap on the charge point.
Your filler hose will only fit the low pressure side, just in case the cap has been removed.

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

How do you recharge the air conditioning system for a 97 cadillac


Just get an R134a recharge kit, and follow the instructions.

The kit contains canisters of oil and R134a and a hose with a gauge on it.

Add about 2 or 3 cans of refrigerant on a system where the refrigerant leaked out.

One may also want to add leak sealer. which comes in a can like the pure 134a.
