Pete. I have a 2000 buick lesabre limited that suddenly lost

Customer Question

Hi, Pete. I'm Sandy. I have a 2000 buick lesabre limited that suddenly lost all electrical activity to the interior and the horn kept honking. It also will not crank and the 15 amp fuse in the back seat fuse box keeps blowing. There was also a strange clicking noise coming from the aforementioned fuse box. I've checked the battery, tested okay 12.7 volts. I also checked power at both fuse boxes and they checked out okay. Replaced blown fuse and it blows the new ones immediately. Had to pull the mini relay for the horn and I have disconnected the battery.

The fuse that keeps blowing is in position #29 in the back seat fuse box. It is a 15 amp (blue blade style) fuse and according to the fuse diagram it is for IGN SW.
