The speedometer not working right why? and the left front seat want move why how do i fix it what is causing it not to move? i can hear a sound when i press the seat switch.


A few possible issues that may cause your speedometer to not work are a bad speed sensor / gear. Could be an internal gear inside the transmission, not as common of a problem.

What type of sound do you hear when trying to move the driver seat ? Is it a clicking or the motor seat motor running ? This can help determine what may be your problem.

My Speedometer reads faster than than actual speed and the reading to actually increases ex at 20 mph it reads 28 mph and at 55 mph it reads 80 mph. How can I correct this?


Do you have any codes ? Have you modified your steering/suspension in any way ? Have you changed the size of your tires ? If you can share more detail information, this would help

My 05 Focus speedometer is wacky. All other gauges and systems work fine. The speedometer needle doesn't go to zero when vehicle stops moving.


Sounds like the speedometer is faulty. If the speed sensor were the problem, the odometer would not work correctly, the transmission would not shift correctly, and the check engine light would be on.

My speedometer is not reading my speed! My accelaration and the power to go is completely there. If I'm on the freeway or parked, gauge says that I'm still going 25 mph. The gauge does move, but is FAR...


If the odometer is correct, the problem is in the speedometer head. If the odometer is also not accurate, it may be the speed sensor in the transmission.

have you changed the wheels and tires on you vehicle to aftermarket ones? if so, the chrysler dealer can "relearn" the new tire size that is on you car, adjusting the speedometer accordingly

Speedometer not registering correct speed.


Has to be calibrated on a rolling road with the correct software ,or you have the wrong size tyres fitted ,they are low profiles making the wheels go round faster in relation to the speedo calibration

I own a 2003 2500 HD Silverado with roughly 110K mi. I noticed my gauge telling me that I need to "change engine oil" one week after having oil changed! A day later I compared my GPS speed to my...


Hi, I think 2 things have happened. 1st, when your oil was changed, the technician did not reset the oil life back to 100%. This can be done by turning the key on, without starting the engine, consistantly push the accelerator to the floor fully, 3 times. At the last time, the oil life should reset to 100%. The other issue sounds like a different size tire may have been installed, causing the speedometer to read incorrect. A dealer should be able to reprogram the computer to accept the correct size tire, therefore making the speedometer read correctly. This should not be an issue, unless the current tire size is not accepted in the computer, at this point, you ned to change to the correct size tire, or realize you may be off on the speedometer, and accomodate for your speed accordingly. Good luck...Coop

1986 Nissan 720 4x4 pickup truck. Speedometer shows faster speed then going (ie driving 10 mph; speedo shows 60 mph.


Either the gauge is bad, the cable is kinked or the speedometer connector is bad...at the tranny.

Speedometer Gauge Slipping - Inaccurate Reading


I had a car that did this to me. It started happening last year so I took it in and they were baffled. Lesson learned never take a car to a big chain store for a difficult diagnosis.They just told me to let my car warm up for 5 minutes and it would be fine. If I let it warm up it was good. This winter it started doing it again but it would do it all the time even after I let it warm up. I never bothered bringing it in again because it was dieing. If you are truly concerned take it into a mechanic ( a good one) and have them diagnose it. Your spedometer cable could just be wearing out.
