First. Check all the lines, condensor and such. Maybe get some of the leak dye stuff.

Second, our cars use R12. You can do a change over to R134 but, it's kinda extensive. You can search for that one.

If the pressure is too low in the system, the circuit to the a/c compressor will be open. I'd suggest going to your drier/accumulator and disconnect the two wires to the pressure switch on that item. Jumper them together and then turn on the a/c. The compressor should run. If it did then the system is low. IF it did not, then you've another problem.

If it did not, go pull the a/c relay out and check for voltage to the X1 pin on the relay with the a/c turned to ON.

Edit: Forget X1, not applicable to RX. The LW or blue/white wire should have a gnd on it and the RY or red yellow should have 12v with the a/c ON.
