I installed an after market audio system into my 2004 Denali and during the install of the fuse onto the battery the terminal sparked. Once this happened many of my monitors are not working and are displaying "Service ...". My alarm no longer works (which affects the automatic door locks obviously) and the passenger door has NO power once so ever. No automatic locks, no windows, no heat seaters, etc... Is this a fuse problem? What is recommended that I do? I haven't went over the 100k GMC warranty and have only had the vehicle for 7 months. Should they cover the warranties even after the after market audio was installed?
