2005 Chevy Tahoe Speedometer

Electrical problem

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?

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

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

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?

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?

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?

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

Any ideas on this as I just ran into the same thing today with my S10
