I have a 1995 chevrolet Tahoe 4 door. For some reason, only my passenger door soeaker and my cargo area left speaker works. At one point all of them did work until i hit a bump in the road. I checked my fuses for my cigarette lighter accesory and it was blown. When i went to replace the fuse, the fuse immediately blew as soon as contact with the metal was made. For some reason my cigarette lighter will work with a blown fuse. I also read that the speakers pull power from that fuse. Not sure if it is true though. My other cigarette plug ins do not work anymore tho after one day it sparked up on me when i plugged my phone charger in. Suggestions? Thank you!
