I replaced the WOT relay and have a full a/c charge. No leaks detected when I had the system serviced. The problem is that my a/c is hit or miss. Blows cold sometimes and warm others, as if the compressor stops running. Seems it starts to blow cold again when I rev through the gears coming from a stop but will warm up when cruising. It sounds like it could be that the compressor isn't getting enough power. I'm running an electric fan (on 100% time because its wired to a toggle - I know I've got to get a controller) without a 3g alternator. At idle, the gauge reads about 11 to 12 volts. Seems logical to me but wanted to see if that sounds right to you guys, thanks.
