Low refrigerant charge
By buying an AC charge hose and a can or 2 of R134a freon (depending on how much your car needs) Attach hose to the low pressure side & charge system. Do not overcharge, or you may destroy the AC system.
Because it probably has a leak if you have just fixed a leak then you need to put a vacuum on your AC system before you can charge it.
You will not be able to charge the system correctly plus you will have moisture stuck in the system.....
It is on the accumulator.
Not the high side.
You charge the ac system on a vehicle through the low side port. There is alot of DIY (do it yourself ) tools in the market for you to work on your ac system. You can find a lot of helpfull information on www.idqusa.com.
The amount of oil charge required for an automotive AC system is specific to the car. There is not standard amount for all cars.
Most Likely refrigerant charge is low -- compressor will not engage unless system has proper pressure
The ac system is probably low on charge. You may have a leak in the system and have lost most of the 134R gas.
