Call your local dearship with your vin, and ask if the special policy for the IPC (cluster) appies to your truck. Some of these have a special policy which would mean that you could have it fixed at the dealer for very cheap. Otherwise you will need to have the cluster sent out and it will need to be repaired, it's not very cheap either, and it will need to be programed at the dealership also after it's replaced.

Really common problem on Trailblazer instrument clusters I've seen it many times in fact I just repaired one this week for a customer. The motors behind the gauges tend to fail once you get a some mileage on the vehicle, usually right after your warranty expires (go figure right?).

SOURCE: Both speedometer & tachometer not working, both reading wrong.

There was a recent class action law suit settled with GM for this exact problem. You can google gm speedometer lawsuit and get lots of information. Unforutunately for most people I think the warranty was limited to 7 years and 70,000 miles. Which isn't a lot of miles for most people.

If you car isn't covered by the warranty there is a way to "reset" the speedometer.

You can turn the ignition slowly like you are going to start the engine. There is a very small "dead" space where you will see your guage lights go off.

What you want to do is cycle the ignition switch from off to that dead space. Each time you do it your stuck speedometer will move towards zero about 10 mph. So if its stuck on 40 you will have to cycle it at least 4 times.

At first you will probably actually hit the ignition and the engine will try to start.....just release it and try it again.

I know this because I have a 04 avalanche with 80,0000 miles and it has this problem about twice a month.

98 ford contour 2.5l standard trans shows mph in reverse and 40 mph at appr 5 mph

I had a '94 Subaru Legacy that would, without any warning, show extremely excessive speed readings (80 -90 mph.) when I was going only 30 - 40. I never did figure it out, but eventually it totally stopped doing that. I realize this is not an answer, but I suspected the speedometer cable, although I never confirmed it. That almost surely has to be the culprit. You might try and disconnect it, wait an hour or so , reconnect it and see what happens. Good luck !!!

It is a 4x4 and I cant find the speed sensor that operates the speedometer. The speedometer sticks at 100mph at a dead stop. It also jumps around between 75 and 80 at random when I am only doing 45 mph.

On our Lincoln, the problem was the Alternator shorting and energizing the ground circuit with Positive juice. Our speedometer and odometer were both affected.

We had miles advancing and 45-50 MPH at a stop. Then inaccurate readings while the car was moving.

Car-stuff.com seems to have the best price for the actual speed sensor which is located in the differential @$11.94.

Please rate my solution and I hope I was helpful.

I have a 2005 Trailblazer and the speedometer was working I stopped at a stoplight & it stopped working. Doesn't move at all.

Hi,

Pretty common issue with the 03-06 Trailblazers. What happens is the motor behind the gauge wears out over time, eventually more gauges will stop working or start acting crazy.

The speedometer and tachometer problem on your Trailblazer instrument cluster is very common on the 03-06 models. It's caused by failing stepper motors on the cluster's circuit board and can be fixed. Check out this page for more on how to get it fixed - Trailblazer tachometer problems

I looked down and the speedometer in my 05 Trailblazer said I was going 120 mph. When I stopped and put the car into park, the speedometer stuck at 70 mph. I need a simple, cost effective solution. Please...

This is a very common problem with Trailblazers and is caused by a fault speedometer stepper motor - the actual motor that makes your needle move around is wearing out.

You have two solutions, if your Trailblazer has 70k miles or less you can take it to your local Chevy dealer and they will replace it for you as part of a recall.

If you have over 70k miles visit my Trailblazer speedometer page here: http://drspeedometer.com/services-i-offer/trailblazer-speedometer-repair
