20 Most Recent 2013 GMC Acadia - Page 8 Questions & Answers

You buy the GM factory manual and then use the wiring diagrams to track down the systems the fuse supplies power to, and one by one you go through each circuit until you find the short circuit. There is no cut and dry way that works every time to find this type of an automotive electrical problem, I have been doing auto electric for 25 years and seldom does the same repair fix more than one car or truck. You can also rent the manuals for download at this site for about $40 per year, a great deal. www.alldatadiy.com
