A/C problem
Hey there fam just wondering if I could get some help with my a/c I'm not getting or at least I think I'm not getting power to my compressor clutch cause when I check the wiring coming from the truck side with a volt meter at 200 volts DC setting it shows 0.1 with it set to max a/c and 0.2 when I turn it off I do have fluid and pressure in the system. It's on a 2000 dodge 3/4 ton 5.9l 360 gas jobber

First off, set your meter to the 20 volt range. Next, try jumping the safety switch on the receiver and see of the compressor engages when the system is turned on. If the compressor engages, then you may have pressure but not enough or the switch is bad. Most likely you just have low pressure and the safety switch is doing it's job.

So ol, grouch I tried that and as soon as I start the truck with a/c on it blows the 10 amp fuse on the distribution block under the hood oh and it shows 13.88 on the 20 volt selection (edit) now all of a sudden it keeps on popping the 10 amp fuse whenever I turn the a/c on

13.88 means your charging system is working properly. Like HeyYou said, blowing a fuse indicates a short somewhere. I'd look for frayed or gnawed wires somewhere in the circuit. If you've had rodents in there, they can cause shorts in really hard to find places. Keep your volt/ohm meter handy. You'll need it to find a hidden short.

Does it only blow when you turn the a/c on or does it do it with the heat? I was in my 30's before I had a personal car with working a/c. Heat though, that's a little more important if you want to see out the windows.

The AC circuit it easy, There is not much to it. If it's blowing the fuse try disconnecting the coil on the compressor. If it doesn't blow the fuse you found the problem. If it does you need to find what is causing the short. Are you sure it's a 10 amp? My 96 takes a 20 amp(compressor circuit).
