Subject: '88 9000T A/C Question

I have a question regarding the A/C system on my "new" '88 9000T. I had the system recharged this last week, and it's holding just fine. I noticed that the compressor did not kick in when the ACC was set to "LO" and the system was out of freon which is to be expected. Now that there's plenty of freon, however, the compressor still does not operate. I wired a hot line directly from the battery to bypass the circuitry, and the compressor is fine, and there is abundant cool air. Sounds electrical... I checked the fuses first, and they were all fine, expect for #4. In the #4 fuse holder (marked: AC) there is a metal connector on the right side but nothing on the left. I removed the glovebox and fuse panel and noticed that the one wire in fuse #4 is green and comes off the #5 fuse (APC) directly below it. I had hoped that it would be as simple as pushing a wire back into the plastic fuse holder, and maybe it will be, but which is the right wire? There are a few wires loose back there, and there are even some that are plugged into fuse slots marked empty for some reason. My guess is that someone had hooked it up incorrectly before. I have a two questions: 1) What exactly is the #4 circuit responsible for? I notice that the A/C compressor itself is on another fuse. Is the #4 even needed? 2) What wires connect to the #4 fuse? What are theirnumbers/colors/gauge and where do they lead? I'm sorry that my first post to has to be a request rather than a contribution, but it's a hot, humid day, and the local library out here in rural MN doesn't have the largest selection of foreign repair manuals and wiring diagrams available to it. Thanks for your help. Jason -- Jason Hill
