Alrighty so I’ve got a 2000 blazer (4x4, 4 door) and I have no power to the OBD2 port under the dash to hook a scanner up to. I’ve checked the cigarette lighter fuse and it’s fine, I even directly hard wired it to bypass the fuse completely and nothing. The cigarette lighter works so I know the fuse is getting power. What else could it be? I used a test light and probed all the pins on the connector but I have no power going to it weather the car is running or not. Thanks!
