If you own a GM product 2003-2006 and have 1 or more instrument gauges operating erratically, this could be a common problem with the OEM stepper motors. They have replaced these with an updated part number. I can resolve this issue for $40 + $5.00 per stepper motor. It is recommended to replace all stepper motors. You can bring/ship the cluster with prepaid return shipping included, or I can remove the cluster for an additional fee. Shipped back to you 24 hours after receiving.
