2005 Chevy Tahoe Speedometer

SOUNDS LIKE YOU ARE RIGHT ON THE MONEY, IF NO CHECK ENGINE LIGHT AND SHIFTS OK, THIS ELIMINATES WIRING OR SPEED SENSOR, MUST BE THE CLUSTER.

From time to time, my speedometer works fine. lately, though, it may not show any speed at all, or it will get stuck on a speed and not drop below that speed, even stopped. Right now, the truck is sitting in the driveway not moving, but the speedometer shows that it is moveing about 75 mph. What could cause this? Is this something I can fix, or do I need to go to a mechanic? Is this an expensive fix?

does the mileage on the odometer or trip meter change at the rate that you would expect it to.

like if you are on the highway, going with traffic, does it take about a minute for the miles to go up by one?

the odometer appears to be working properly. based on the gas that i am using, i am traveling the expected number of recorded miles.

then you've got a bad speedo head.

the signal from the speed sensor drives both the odometer and the speedo.

Noticed the speedometer sticking at first, then jumping way beyond actual speed vehicle is going. When we shut engine off the speedometer often sticks at 20-30-50, does not go back to 0. Now the speedometer has gone beyond the 120mph and jumps back and forth.

What can be causing this and how can we fix it--hopefully without having to take truck into the shop.

Thanks

Inspect and test the vehicle speed sensor-

Last month my speedometer stopped working correctly. When I was parked after running it for 15 minutes the guage would not got up with speed. Last week I was driving and the speedometer pegged out fully and only comes down to around 60 in park. Should it be replaced or can I recalibrate it by taking the guage unit out? I have replaced a guage unit on an escort and neon when they stopped working but those had many problems.

Can the sensor be "do it myself" replace or should it be done by a mechanic?

Sould be done by a professional/ Tech bring here in

When i turn my key on my gear indicator light comes on. But when i start it the indicator does not come back on and my tach does not work. If i start driving the check gauges light comes on and the transmission acts like its in overdrive and the speedo does not work. then the indicator will come on and the check gauges light goes out and the speedo will start working sort of, not very accurate but works. The only thing is once in awhile i will start it and everything works fine. So what could possibly be wrong and what can i check to see and start eliminating things?

clean any ground wire that yo can find. this includes battery to engine, engine to dash, frame, anyo o them and see if that helps.......

My speedometer isn't working properly, that is to say when it is very hot outside or after I have been driving for an hour or so, the speedometer stops working normally. By this I mean it either sticks on my current speed and doesn't move no matter what speed I am doing, or it will stick temporarily, then starts to work again so that when I come to a compete stop the speedometer will read anywhere from 10 to 40 mph. When it does this, the only way I can get it back to zero is to repeatedly crank the engine and then turn it off, until the speedometer returns to zero. Early in the mornings when everything is cold it works fine. The remaining gauges(tachometer, battery, coolant, and oil) all work normally no matter what the condition. My question is this. Is my instrument cluster bad or could it be the sensor for the speedometer?

Cluster failure is very common and it was replaced for free if under 90k miles at the GM dealer
you can call your local GM dealer and ask them to check if your covered
use a scanner tool select data and go to speed
drive truck scanner should show the speed if cluster and scanner showing two different speed cluster at fault

I drive a 88' s10 tahoe (2.8L Ext Cab), 112,000. Just recently I took her on a long trip (Knoxville TN to Harrisburg PA). I always change my oil and do basic tuneups before i leave (changes plugs, filters, etc if nessacary). Over the past couple of months occasionly the speedo would freak out and would start bouncing between 70 and 80 when i was really doing like 55 or 60 (and it would only do it in 5th gear). However as i was on my way home, It stopped working all together. The Check Engine light came on and the odometer and trip meter stopped working. Even with a few whacks and shakes nothing happened. I still have my others gauges just no speed or miles. I know it is mechanical (I removed it once to fix an electrical problem) and considering the pictures in my manual dont make much sense and dont resemble anything in my truck, i was wondering if you could break down how it works, and where my problem is (and how much it may be to replace).

Thanks, Dan

Just bought a 03 chevy tahoe. We drove 300 miles to get home all well then suddenly the speedometer quit working showed 110 when we were going 70 then the needle feel past the 120 and doesn't move at all now.

There are two diiferent places (at least) that will repair your speedometer for about $100 plus shipping. It's easy to pull the instrument cluster, pack it up and send it. Check ebay or google the problem. It is the stepper motors in the gauges. You can drive the car without the cluster for week if you're careful. I got by a couple of months by bumping the starter a few times without letting the engine start and that dropped the needle back down (eventually) to zero. But the problem does not go away.
