[12Ounce]

If you have a small leak but have not lost ALL your refrigerant (i.e, the compressor comes in but only for a few seconds) you may have luck with one of these off-the-shelf 134a recharge kits that is nothing but a pressurized bottle with a pressure gauge and hose attached. These things are available at all aftermarket outlets such as Advance and AutoZone.

The idea is you hook the provided hose to the SUCTION side of the compressor .... usually the fitting on the larger tubing. When the compressor comes in, it will reduce the pressure on the gauge. The lowest reading should not be lower than 25 psi. You squirt refrigerant into the system until you get the lowest reading to be between 25 and 45 psi. Not higher ... not lower.

Follow the instructions on the container ... especially those concerning eye and hand protection.

If your compressor does not now come in at all ... then you likely need further technical help. You can watch the ac compressor clutch engage by looking down on it ... may require a flashlight. It will "click" when engaging .. but disengages rather silently.
