LeSabre 2005 speedometer whacked out

My speedometer started acting whacky at first by showing intermittently 15 mph under the actual speed. After about 2 weeks, it started totally whacking out, being way to high, way to low, or not showing at all, varying it's response within the same drive. It does go back to zero when car is shut off. Easy do-it-yourself fix?

    Thanks for the rapid response! Now for Part 2: the gas gauge whacked out first, then the temp gauge, finally the speedo. I didn't bother about the gas and temp gauges because I have the info panel to tell me that vital info, however, it doesn't tell me my speed. :) So, I reckon I need to replace the intrument cluster. How about that? Do-it-yourself-able?

This is an electronic speedometer, nothing is user repairable, the circuit board fails and you get your problem, you will have to pull the speedo and send it out to an authorized GM repair station, they are all over the country, one company that does this is called SPEEDOTACH, LOOK THEM UP ON THE INTERNET.

    Yes it is DIY, but U will need the info off the cluster to get the correct unit, there are calibration issues.

My speedometer suddently started reading 130 mph when I'm definitely only going about 40-60mph.


If the odometer is ok, the problem may be in the speedometer itself.
If the odometer is also acting up, the problem may be in the speed sensor in the transmission.

Speedometer does not work correctly all the time. Cold weather seems to make it go hay wire. Never stays stuck when the engine is off but registers 15 to 50 mph faster than actual speed


check and see if the wire on back off speedomter is loose and check your vehicle speed sensor see if working or broke and you also have wheel speed sensors that could be malfunctioning

Sound like the speed sensor is not working right. Located on the drivers side of trans where the speedometer cable plugs in to the speed sensor. One 10mm bolt with clip holds it to trans.

You most likely have a defective gauge cluster assembly. GM offers repaired clusters for some models, but they can be costly. (300-400bucks)

Replace the speed sensor, but also make sure you clear any codes, even if none are showing up, disconnect the battery for about 1 hour. After that drive it easy for a while, so it can relearn.
