I have a 89 mustang 5.0 lx and my a/c just stoped working also. I got a refill kit and tested the pressure and it was low. So i filled it up to the recommended pressure and it still doesn't turn on. The blower is on but the compressure is off. I was wondering how you hooked it directly to the batery to test it. Mine has 2 wires to it. I can turn the pully manualy so i know its not frozen.
Any help would be greatfull
