Ok here goes. I have A 2001 s10 Blazer. 2wheel 2dr, completely base manuel windows and locks. I was driving home from work tonight and the security light came on and stayed on and I lost all my lights. Dash lights come on but neither the interior nor neadlights nor the running lights work. Not really sure if they are related but this is the first time the security light has ever come on at all. Any help would be greatly appreciated. Never was very good at electrical. Thanks again in advance. Oh and the truck starts and runs fine so I am completely lost.
