Charging air conditioning - 1996 Toyota Camry

The port in the larger of the 2 AC lines from the compressor is the port you charge at.

Is the compressor running when the engine is running ?

Instructions

1. • 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
     

EC stands for air conditioning. Have you charged the air conditionning with gas. is the air conditioning pump making a clicking noise when you press the EC button.

You may have created an over charged condition and at this point the a/c compressor will cut off on high head pressures. This can be verified by installing gauges to the systems high and low side service taps and reading the pressures.An overcharged system will start the compressor briefly but soon cuts off once pressure goes to 350 - 400 lbs on the high side. Acceptable pressures for this system should be no greater than 250 high and low suction should drop to 40-50 psi.You might recover the charge and evacuate the system,then try bringing the charge back to proper level.A sight glass in the reciever drier really helps determining proper fill.Once all bubbles have dissipated from the sight glass during charging ,one should stop at that point to avoid overfilling.Too much freon is worse than a low charge especially in hot ambient conditions....

Did you have compressor checked to make sure it is not the problem? Or did you just charge due to lack of cool air? Some parts stores can check it. Garages too.. If not the prob let me know..

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.

Low refrigerant charge or a sticking blender door. Check the suction line for temperature. A cold tube means that the charge is fine.

If the system isn't cycling on and off every two seconds then the charge is fine, your evaporator may be clogged. It might be more cost efective to send it to the dealer.

start with charging the system with r134, be sure to check the pressure before charging
