fuse and check engine problums
Hello, I am new here. I'm having a hard time with my truck. The #9 fuse, which controls the dash lights, parking lamps, tag lights and rear running lights. I have replaced the fuse twice now; it is supposed to be a 20 amp. there was a 25 amp fuse in first, and when that one fried, I put a 20 amp in. That one didn't last even last three days. The one I have in now is a 30 amp fuse. The other thing(*) I am having problem(*) with is my check engine light. It says that my O2 sensor, and my brake switch are insufficient. I have already replaced my O2 sensor twice in the past year and a half, and the check engine light is still on, and it is still saying bad O2 sensor. I don't know where the brake switch is.
