Hello all,
After doing some research with the Haynes book I found the fuse location for the interior lights that have been out for about a month. I pulled the radio fuse (10A) and as soon as I tried to plug it in it immediately blew with a nice bright spark. I realize this hot all the times so should I disconnect the battery to install a fuse then check it? Thanks.

just push it in. When the radio is first power up, the cd mechanism initializes which is why you are getting the spark.
Give it a quick solid push and you should be ok
