Subject: '88 9000T A/C Question

I'm having a bit of a problem troubleshooting the A/C system on my "new" '88 9000T and was wondering if anyone might be able to help. Here are the facts: I had the system recharged this week, and it's holding it's charge just fine. It had a big leak and was completely out of freon, so I wouldn't have expected the compressor to work when I set the ACC to "LO." Now that it's fully charged, however, the clutch on the compressor still does not kick in. I was able to bypass the circuity altogether and run a hot line directly from the battery to the compressor and get the system to put out cool air. Must be an electrical problem... I went to the fuse-box, and everything looked fine except for that in the #4 fuse holder there was only one connector. I took the glove compartment out and removed the fuse holder and found a few lines loose with connectors, and a few even connected to sockets marked "empty." Very confusing. On the right of the #4 fuse holder is a green wire which runs to the fuse holder directly below it (#5, APC). There's nothing on the left side at all. Could someone answer the following questions for me? 1) What is the circuit containing the #4 fuse actually responsible for (I notice that the A/C compressor is on another circuit altogether?). 2) What wires should be running to and from the #4 fuse? The loose wires I have are numbered, so it may be as simple as plugging one of them back in. I'm sorry that my first post to has to be a question rather than an answer (or some other sort of contribution), but it's a hot, humid day, and the public libraries out here in rural MN don't carry many foreign repair manuals with wiring diagrams. I appreciate your help. Jason -- Jason Hill
