Its strange, I found out that the ign1 fuse on my 94 sedan deville was blown so i replaced it. I went to get some gas and my ac didnt work, so I checked it again and the same fuse blew again. The fuse will only blow after I start driving, its very odd and strange. When the fuse blows the controls for the twilight sentinel/trunk switch/fuel door switch doesnt work and for some reason causes the fuel level gauge not to work. I brought it to cadillac and they couldnt find anything wrong with it and they were blaming my stereo because it wasnt stock. Anybody have some idea on what could be the problem?
