I purchased an aftermarket recharge kit for my 2000 windstar. i assumed it would come with detailed directions, but did not. Any help would be appreciated. I was told I have to put the kit on the low pressuer line, but don't know which is which. I was also told you have to be careful not to overcharge on the high pressure side, how do i know? Tks
With aftermarket kits, you can't screw it up. The fittings are two different sizes so you can only hook it up one way. They sell new kits that have gauges built onto them to show you when to stop putting freon in. That should prevent you from overfilling.

It may be difficult to find a company that services window air conditioners. You will need to look locally for repair service, where you live. Look in the yellow pages of your area or do a search on the web.
The link below is for a video that explains how to recgarge a window air conditioner, for the DYI.
If your air conditioner needs recharging it is because the refrigerant chemical is leaking out of the system. Many people think that air conditioners naturally leak refrigerant, so they assume they have to take the car in every year for recharging. This is not true. The refrigerant is not supposed to leak. If the refrigerant is low, find and repair the leak. There should be no reason for a recharge.
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.

3Turn on the airconditioning 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
Lack of Coolant wouldn't cause your AC to blow hot air.
You may have a vaccum leak in your dash board that is causing your heater to remain stuck.
If not this, then you will have to have your AC recharged. You can purchase a recharging kit from your local auto parts store! Fortunately, your vehicle can use the newer type of AC Recharging kits so you have many options!
go to a parts store such as Advance Auto Parts or Auto Zone and buy the A/C recharging kit they have with the rubber line and connector that connects only on the side that you need to recharge your system. If you can put air in your tires you can out freon in your a/c system.
