2004 LeSabre dash noise? Errrrrrrrrrring

[tcpalmertw]

Are there any motors in the dash on drivers side that can cause a medium pitched errrrrrrring sound that comes and goes and changes loudness a little? Sound stops when volts drop for a second. If so, how can one pinpoint the source? Many thanks!!! Tom from Texas

The only thing that comes to mind is the actuators for the climate control. turn the fan on low and set the temp at 75 or 1/2 and set the direction to vent with the ac off

The instrument panel does contain 4 small stepper motors that drive the tach, speedo, temp, and fuel gauges. I've not heard of them making nosie (pun intended).

They do make a noise when they move fast enough. My 2000 lesabre custom had a bad fuel level sending unit and when it got below half it would go to e for a second than back to full, making that sound as it moved.
