ACC fuse blowing randomly, not the cig lighter
Pretty self explanatory, i blow this fuse anywhere from 1-3 days of daily driving. Not sure if it blows while driving or not, just that when I go to start her up at night nothing on the circuit works since it's blown. Searched here for hours and only came up with the cig lighter which i unplugged and still have the condition. Any other problem areas to check? It just started recently and nothing new has been added to any circuits so I'm stumped.

Re: ACC fuse blowing randomly, not the cig lighter
For a fuse to blow there has to be a short usually, the usual suspect is the cigarette lighter which you said is disconnected, is the plug just floating around in the dash? It could be grounding out. Your courtesy lights are also tied to the circuit, check the dome light bulb and make sure its not corroded at the contacts or anything like that. You could replace the cigarette lighter with one from orielys, they're like 5$ and they take about 2 mins to put in, if you get one in and the problem stops you found the culprit. If you haven't added anything or modified and circuits then you're really limited on what it could be, use austinthirdgen.org to find the wiring diagram for your car and see what exactly runs on that circuit for your car, then check each system from there. There's a bug somewhere, you just have to flush it out.
