my temp gauge on my base 2005 4.3L is acting up and now stuck on the hot side. My check engine light is only on because the picture is taken while the car is not started. please give me any ideas what you might think is wrong thanks.

My wife had the same problem with the speedometer. I replaced them all with updated motors I got from Ebay. Fairly easy job.

 

[ebenz21]

do i need to re calibrate the gauges if i take them off ? and what model motor did your use ?

 

[brigoyanks]

recalibrating is very easy...just have the engine cold and put the key in with the ignition to on...DO NOT START IT ... and put the needle at the right spot..then take it back out and put the plastic cover back on

Tricia, its really a pretty easy fix and a known problem (even if GM won't admit it) with the 2000-2005 Impala dash clusters. The stepper motors go bad, which is what has happened to the OP's temp gauge.

It falls into the same category as the Catalytic Converters, Fuel Level Senders, and numerous transmission issues that these cars are known to suffer from, and that GM has quietly ignored.

2005 impala 3.4 my tempature gauge message center is doinf the same thing going all over and the cars not running hot

 

[zerialz]

A stepper motor (or step motor) is a brushless DC electric motor that divides a full rotation into a number of equal steps. Behind each of the needles on the cluster there is a stepper motor with plastic gear teeth.. With age they strip and end up getting stuck in position or reading inaccurately.
