Low side only, this means you have to charge the unit in the thicker line of the compressor NOT the thin line as this is the HI SIDE and the refrigerant bottle could explode.

Air conditioner blows cool not cold air


- Keep the knob on RECIR and not FRESH.
- Put the air con ON, blower on max speed.
- Open the hood, inspect the inspection window glass located on the liquid line.
- If foam like bubbles are seen, charge the refrigerant gas, till the glass window is seen clear. Never overcharge the system.
- If the problem persists, check the following:
Refrigerant volume
Refrigerant pressure
Heater control base (for Hatchback)
Heater control base (for Sedan)
Air conditioning pressure sensor
Compressor and pulley
Expansion valve -
Air conditioning amplifier
ECM
CAN communication
The following diagram may help you identify the components.

2002 Pontiac grand am air conditioner not blowing cold air


Sounds like your refrigerant is low/out. There is a product you can buy at your local wal-mart/auto store called EZ Chill Auto Air Conditioning Refrigerant. I've used this item personally in my own vehicals and it works awsome. One bottle comes with everything you need including detailed instructions and is super easy to put in. Costs anywhere from $25-35. Well worth it...hope this helps.

STEPS TO CHARGING YOUR CARS COOLING SYSTEM:

STEP 1) Look under the hood of you car on the left side of your cars engine. There should be two stainless steel lines coming from a stainless steel cylinder to your cars compressor. The two lines have plastic dust caps on them sometimes they are blue or black. Usally the black has the larger diameter tubing that runs between the evaporator and the compressor. This will be the port that you hook the refrigerant hose up to.

STEP 2) Start your cars engine after you have secured the hose hook up to the air conditioner line port. Once the cars engine is running, turn your cars AC on to Max cool. Shake the can of coolant well. The gauge on the can of coolant should read in the blue but if it is in the green your air conditioners pressure will be between 0-25 pounds per square inch. This means you will have to add refrigerant to the compressor.

If your cars air conditioner pressure is in the blue. The system has the proper amount of refrigerant and you do not need to add. If the gauge reads in the yellow you may want to seek professional help because refrigerant is not what is wrong with the unit and is probably something more technical and most likely something that you do not want to attempt to do on your own. The red on the gauge means do not add any refrigerant at all and to seek professional help.

STEP 3) If the pressure of your air conditioning system is in the green it means it is safe to add the refrigerant. You should wait for your air conditioning compressor to switch on before squeezing the trigger to add the coolant. When the compressor switches off then release the trigger and repeat until your pressure gauge on the coolant can says that the coolant is in the proper range. If the needle on the gauge is in the top part of the blue you have successfully charged your cars air conditioning unit.

STEP 4) Release the attachment from the tubing port and replace the dust cap back in it's proper place and you are done. The cars air should be cool and your compressor should cut off and on less often. If problems persist you should consult a mechanic or someone that has experience with air conditioning systems.

When i turn on my air conditioner in my 1999 durango it blows out hot air. can i put in antifreeze myself or do i need to take to the dealership?


Antifreeze is only for the radiator, does not affect the air conditioner, make sure you have the setting on cold, if it is still hot than take it to your local air conditioner re gas station, most auto electricians do it, dealerships usually send them out which you end up paying extra for!!! You just need a re gas in your air conditioner.

Just to verify. should i take it to an airconditer repair shop?


Yes, if you have a problem with the air conditioner that requires recovery or recycling of the refrigerant, by all means take it to a certified air conditioner repair shop, or the dealer to fix the problem. The tech and the garage should be certified for air conditioning service either by ASE, or by an EPA certified testing organization.

The garage should have the ability to recover the refrigerant when servicing the air conditioning unit.

Good luck on this repair.

How to recharge recharge airconditioner


Hi, determine if your car uses R134 or R12 refrigerant. You will notice screw type connectors on the both the High Pressure Side and Low Pressure Side lines in models using R12 refrigerant. R134 compatible models have quick connect valves on both sides. Models made before 1995 may use the old R12 refrigerant. If this is the case, you must have your Chrysler's air conditioning system retrofitted to use R134 refrigerant. Mixing R12 and R134 refrigerants is dangerous and may cause damage to your vehicle. Check your air conditioning system pressure using an automotive air conditioning pressure gauge. Keep in mind that in order to get an accurate reading, the air conditioner has be turned on the coldest setting with maximum blowing power. Remove the Low Pressure Side port valve cap and set it aside. The location of the port varies, but it is usually in front of the engine block. Attach the refill hose to the port on the Low Pressure Side of the air conditioning system. The Low Pressure Side port is smaller the High Pressure Side port. Because the ports are different sizes, the refill kit hose should fit only on the Low Pressure Side port. Additionally, the High Pressure Side port will usually have a red cap or be marked with an H or the word High Allow the air conditioner to **** the refrigerant out of the can by slowly turning the valve on the refill kit hose. Pay attention to the way you hold the can. Most kits will have you hold the can upright when you recharge the air conditioning system. It may take as long as 10 minutes to empty a single can. Turn the valve to the off position and remove the refill hose from the port. Recap the port before closing the hood. Let the air conditioner stay on for at least 30 minutes. This allows the refrigerant to move throughout the entire system.
Take care
