I recently bought a 97 blazer and discovered that the interor lights do not work or the lighter and rear hatch release. I returned to dealer and they could not find the problem. After looking at the fuse box I discovered a
20A fuse missing from slot #2. Installing a fuse causes everything to work but the lights will never turn off. Is this maybe a common problem? Is there a part of wiring harness that someone can point me to? Any help would be greatly appreciated. A link to a schematic would help too.
