Time for an update. Bought a reman compressor from Ebay, put it in, went to an A/C & Radaitor repair place for a charge. More primative than my autobody friends (no vaccuum), but more knowledge about A/C's. Popped in a charge, and the compressor didn't move. We re-checked fuses, swapped the...

Lots going on now, truck can wait. Should be back at it in a week or so.

@ Budwich It does confuse me. All measurements were with the engine running. With the test light, I got 2 bright lights and a dim one (that also clicked the relay). The meter only showed 12V at one point. I was thinking it's more like a 5V and a 12V source, if it should be two 12V sources...

Used the test light as a power source. Connected one end to the battery, the other went to the red lead going to the coil (only unplugger the red wire, left the black alone). Power straight to the coil did nothing but light the test light. That means the coil is not Open, and with my prevous...

Swapped out the low pressure switch, I have the original from before the compressor change. Still nothing, and a jumper does nothing. On to the relay. Using a trouble light, and the relay unplugged slightly. The "7" and the "O" have a bright light while the "8" is dim, and nothing in the last...

Thanks for the replies. Since all of the relays in the fuse box have the same number, I have swaped the relay around to other positions, and put a different relay back. I will check for voltages, and ground this afternoon, what should I expect to see for the 2 voltages? The system was charged...

System vaccuumed/recharged. No compressor operation. Fuses and relay checked with a meter, then switched with other Fuses and relay. Used a stick to push the clutch, jumped the low pressure switch. No voltage going to the clutch. Baffled and looking for direction...

Well, since the system was fine before I swapped compressors, I figured maybe the hose connector isn't tight enough, or something got scored and that's where the leak could be. I disconnected the hose, and when looking, I saw my problem (most likely). There are two rubber coated, probably...

System is empty. Crap.

Well, I would say that there's no voltage going to the coil. Meter reads 0.179 volts. All fuses are good, so my guess is that it's the head unit. Any clue as to whether they can be repaired?

The unit was a low mileage (80k) junkyard part. I had a friend discharge and recharge the system, vaccuum, oil and freon added using a professional system. Silly me, I checked the Ohm;s, but didn't check for voltage heading to the coil. I guess I have a chore for this afternoon. It's one of...

Replaced bad compressor 2 years ago, and all was good. AC is dead again. Coil reads 3.6 Ohms. I've tried to push on the clutch, but it doesn't move in when running or off. How hard is it to push the clutch in? Is it possible to measure voltages coming to the compressor to narrow down...
