Hello.. Newbie here. My wife has a 2005 Mustang V6 Convertible that has some annoying gauge issues. Currently the tach does not work, water gauge always on "C", and now the battery gauge goes past the high setting. I checked the Cluster fuse and it was not blown.

Are these issues correlated? I saw posts on Cluster and stepper motor possibilities.

Any tips would be great.

 

Yes. Replace stepper motors.
