Hello, I am new to this forum. I bought this 91 4x4 blazer about a month ago, and noticed the gas gauge, Oil pressure, temp gauge is not working. The gas gauge always shows alittle more than half a tank. Sometimes it's erratic, But never goes below half. I was wondering if it is the Oil, gas sending unit, and temp sensor :?: Or could it just be the Instrument cluster? Thank you for any replies.

What kind of car do you have, and you might have more then one fuse box, for example. I have a 2000 bonneville pontiac and my fuse box is under the back seat, and then what they call a rely box, my second fuse box is under the hood. tell me what kind of car you have, and I will let you know if you have more then one fuse box, if you know you donthave more then one fuse box reply back and I willl help you through this mess. reply back either way

It's a [b:252959ec8f]1991 Cheverolet Blazer s-10/t-10 4x4, 4 door, 4.3 liter engine, TH700R Transmission[/b:252959ec8f]. Anyways, I bought a new coolant temp sensor today thinking that might fix it. I was wrong. So I am almost positive it's the instrument cluster. I've checked every fuse again. None are blown.
