any component on the circuit or even the wiring can be shorting to ground or a bad ground. to diagnose a technician should install a circuit current testing device to properly load test the circuit. technician would also use a wiring schematic a fuse block reference chart a power probe and or DVOM. Manufacturers trouble shooting flow chart as well as a search of TSBs and recalls by symptoms. every vehicle when running should also have the alternator and battery tested as too high of voltage or AC leak by can damage components and your problem with component blowing fuse could be result of another problem and not the cause. You can call Kris or Andrew 456-0722 to get vehicle propely diagnosed and repaired at Carmasters. Don't forget to ask for free loaner car if you need one while yours is being diagnosed and repaired, Jim
