1991 CHEVROLET TRAILBLAZER

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.

Check the gauge fuse, it soulds like it is blown.

I had the same problem.

Check the fuses, when the fuses are blown they panel amongst othe things wont work. Check the fuse box. Do you know where that is?

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 1991 Cheverolet Blazer s-10/t-10 4x4, 4 door, 4.3 liter engine, TH700R Transmission. 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.
