Question about 2003 Chevrolet Silverado 1500

1 Answer

03 silverado spedometer and temp gauge are off

I was driving earlier and my spedometer said I was going 70MPH and I wasn't at all, I was probably going about 30MPH. I pulled over into a gas station and when I stopped I noticed the orange thing that tells me what speed I was going stopped at 20MPH. I've tried restarting my car several times to see if that would help and it has dropped a little bit so now when I am in park it says I am going 10MPH. The temperature gauge has also been off, it will sit at 1/4 or 1/2 even when my truck is turned off, it will go back to normal when it feels like it. Also, my truck tells me "low coolant level" which is weird because there is plenty of coolant and there are not any leaks from what I can see. One guy at the auto store told me it might be a fuse and to try replacing that first, but I'm not sure where the fuse box is. I'm a girl and I would like to try and fix this myself rather then get taken advantage of at the dealership (and the car dealerships are closed until Mondays anyways so I really need to get this fixed)
Thanks for the help in advance

The 01 to 06 GM trucks, tahoes and suburbans had issues with the instrument cluster failing. They are under warranty for 75,000. If you are under that the dealer will replace it for free.

If it is only on certain speed and goes away if you drive over/less 70mph, try to do wheel balance and see if it helps.

Insturment cluster stops working All gauges plus speedometer & rpm gauge. Sometimes it starts back on its own on a restart. Sometimes it doesn't for several restarts then it does.


They had a recall on that. We have a 03 Chevy Silverado where the spedometer would either sit at zero or get stuck at the last speed. It sometimes takes a few starts to get it going. We did receive a recall notice for the instrument cluster to be replaced at no charge, but the clause was it had to be under 70k miles. We bought our truck at 72k and it is around 1k to replace so we just live with it. I dont get how the milage would have anything to do with it. Wish I could be of more help...its very frusterating.

2003 chevy silverado, fuel gauge started registere...


Common problem on the 03-06 Silverado instrument clusters for the fuel gauge to go out. It's usually caused by one of two main problems, either the stepper motor on the cluster's circuit board is going out or the sending unit on the fuel pump is going out.

Temp gauge sits normal and after a while shoots to max with warning light visible..fans working no coolant loss..earlier today light came on at 70mph..drove 14miles tonight at average 50..and light did not...


Most obvious question is when that happens, is the engine actually overheating or just reading that it is?
If there are no signs of overheating, I'd check that the temp sender is working correctly and that the wiring to it is not grounding somewhere. Though not "high tech" you can tape a small dial type thermometer that has readings past 240 to the upper hose and check temp when light is on compared to "normal".If readings are similar, then I'd change sender.
Also check the a/c condenser for obstructions. (leaves, bugs, plastic bags etc). That alone can cause strange temp fluctuations.
