2005 FORD MUSTANG--FUEL GAUGE AND SPEEDOMETER DOESN'T WORK--WHAT'S LEAST EXPENSIVE SOLUTION


This is due to a problem with the gears in the speedometer and fuel gauge; there was a manufacturing defect that ford fixed in later years. The cheapest solution is to replace these gauges. I found a local mechanic that knew how to fix it, and did the job for $60. I recommend checking craigslist for a local person, because this is a very common problem.

2005 Ext. Speedometer sometime works sometimes it doesn't. Most of the time is inaccurate.


Replace the stepper motor on the back of the speedometer. Common problem.

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.
