Here is a quick way to find ANY charge port on ANY a/c system.
The low side of the system where the freon goes is allways the fatest of the two hoses comming off of the compressor. The high side of the system is the smaller of the two. And on a 134a system the low side port is the biger of the two. Hope this helps.

Forgot to mention this. If the system has failed the leak should be repaired. And, If you do not pull a complete vacume after the repair your wasteing your time. 134a can be very touchy.I have found that 1/4 lbs either way high or low. Makes a huge differance. Once again. Hope this helps

Heres some pics I have I read the manuel it says something about the high side don.t touch because its the pressure testing port and vacuum port for A/C

This is the one I was referring to that I found

This is around my firewall the A/C sensor

I did find sensor to keep compressor running make sure its not running more than 10 minutes

here this pic on how to jump sensor make sure car is off not running and pull sensor out I used a paper clip even the tips and plugged it in takes a bit a time but make sure you don't bend the pins to bad if you do bend them just bend them back...

i belive it is that is where my mechanic puts in r134a. it should screw off and you will see it.....always follow the directions to avoid injuries.
