normally when that fuse blows (the interior one) it causes your rear running lights at work to stop working, or atleast it did to my car. im going through the same problem for the last two weeks after ripping apart my interior 3 or four times ive decided to turn it over into the hands of professionals. im so fed up with electrical problems i hate that shit. anyway good luck tryin to find the short i dunno even what caused mine. it just started to happen one day. so im waiting on a call back from the diagnostics place now hopefully i can get this done with the car back in a couple days. ill let you know on what they say it is for you to check it out on your car also
