2008 Trailblazer Air Conditioner not cooling. blows warm air for the first few miles then cools. It has been recharged.


Philip, You may have to have a good tech, check,diagnose and estimate repair. Could be a few things causing poor AC, recheck your charge level,check your fan at the condenser, make sure the condenser isn't obstructed, compressor clutch could be faulty, system could be plugged with contaminates limiting refrigerant flow.You say the system has been recharged, was it done properly, if not system could be plugged. AC system should of had system checked for leaks,evacuated, flushed, new orifice tube, then recharged with proper quantities of oil and refrigerant. Check the attached links,instruction and guides, Good luck

I recently replaced the engine on my Citroen c4 2005 model, now the warning lights stay on, the engine overheat, abs and anti pollution warning lights stay on.


The problem for engine overheating rise due to insufficient refrigerant. Try recharging the refrigerant tank with fresh refrigerant and water. If the refrigerant in the tank is of poor quality then also engine overheat.

The reason for ABS light to come may be due to air in the brake fluid line. Try brake bleeding to remove the air bubbles. Also the faulty brake actuator line may cause the problem. Check for actuators on each wheel.

Pollution warning light comes on if the exhaust system not works properly. Check for faulty Oxygen sensor or faulty catalytic convertor.

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?


Air conditioning uses CFC gasses to cool air. These gasses, should they be released into the atmosphere, could cause harm to the environment. Most countries mandate that a qualified person carry out the maintenance work.

If you live in a country that allows DIY AC recharging, there are kits available to cycle out old gas and cycle in new gas. You need to get the right refrigerant for your car, and most codes can be found online.

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.

Imtermittent fault with Ford Focus air conditioning


Sounds like a leak. If you've had to recharge the system every year, you're losing refrigerant. If you've added refrigerant on your own, you may have overcharged the system. The best way to find out is to get a refrigerant pressure gauge and check the pressure. A reading between 30-40 psi is in the normal range. Below 30 will require a recharge, above will require releasing refrigerant.

Air condition suddenly blowing uncooled air.radiator full. worked great until yesterday. could it be thermostat?


The thermostat and radiator are part of the engine cooling system, not part of the air condition system. Chances are, the A/C system is low on refrigerant. The system has a low pressure switch that prevents the air conditioner compressor from being damaged with the Freon is low.

You can purchase a can or R134a refrigerant at any parts store and try recharging the system yourself….the basic instructions can be found here:

Air and heater blower


If you are losing refrigerant (that vehicle uses 134a) there is a leak somewhere. If you are not losing refrigerant, there are several things that you can check.

You say you replaced the refrigerant twice and recharged it twice. Was the system evacuated and recharged, or did you just use a DIY kit.? With 134a too much is a bad as not enough, an overcharged system will not cool!

A bad expansion valve will allow system pressure to build, and will make the compressor work harder, which would account for your feeling that the A/C is taking power from the engine.

A bad radiator cooling fan will do the same thing. Does the radiator fan come on when you turn on the a/c?

The heater control valve could be bad, or the air mix door not working properly, allowing the heater to be actually heating the air conditioned air. If the a/c actually gets warmer than the outside air, then this is what I would look for first! It may be as simple as a vacuum leak in a control line!
