I have an '89 LX 5.0, and was hooking up a radio (I put in radios without any problems), and the dash lights went out. Checked the fuse and it's fine. The dome still comes on when I turn the dimmer, but no dash lights. Removed the radio. Still nothing. I pulled the radio fuse, put it back it and it makes a noise near where the radio was whenever i put take it out and put it back in again. The noise sounds like a spark, but I see no spark. Any idea guys?
