has anyone done a charge on their ac? need to know where the compressor switch is and some instruction please.

 

u shouldn't need to noe where the a/c compressor switch is. Just turn on the a/c from inside the car. The compressor won't spin until there is enough pressure in there. Just hook up the charge to the low side tap the can and let it rip. You're not going to know how much pressure is in the system unless you have a a/c gauge. So just to be safe after a can see if the compressor is spinning then go inside and see if it is cold if it isn't spray the condenser with water then add another can. Don't go crazy by adding a lot because you can freeze your compressor then your in dodo and need to buy a new compressor.
