the trick to the DIY kits is to not follow the instructions
...well, not completely. obviously you need to have the AC on, fan on high, and doors open. if you dont have a can of mixed refrigerant and oil, get a can of oil, put that in first. before you hook up the can of refrigerant, get a wet rag and soak it in HOT water, and use that to wrap/hold the can. the instructions say to hold the can upright, but i find it best to gently shake the can, alternating from upright to upside down. (especially upside down if the refrigerant is too low for the compressor to kick on) after you get the can in, check the level with a gauge. continue as needed
