Hi! I'm new here and I have a couple questions. My 05' Aztek that I'm restoring has a broken speedometer that's permanently stuck at 45. Would you guys recommend replacing the whole cluster or trying to repair the stepper motors myself? Second question: I called a local junkyard and they said they had a cluster with the Driver Information Center that my Aztek didn't come with. If replacing is needed, would the DIC work with my car?
