Hey guys,

Quick question,

Is it normal for the stepper motors in a 2006 trailblazer to "click" and sometimes grind. It is really noticable when first starting the car, and when idling, aswell as on shut down. During normal driving I can not hear it.
As always any help is appreciated.

I can hear my tach motor. I'll probably change it out one of these days, but I guess it doesn't bother me that much. I don't think the stock motors were of very good quality.

Great thanks for the quick reply. They seem to be functioning fine, its just annoying! I probably am not gonna do anything until the stop working, its just better to know its a common issue.
Thanks!
