where is the onstar fuse located in a 2002 GMC Sierra 3500 extended cab?
Hello,I will be glad to try and assist you with this,Welcome to Just Answer.


The fuse that powers the On star control unit is located in the drivers side fuse block,it is labeled SEO IGN and is a 10 amp fuse.

This fuse also powers the selectable ride switch on the dash if the vehicle has the adjustable/selectable ride.If it does not then this fuse only powers the VIU or On star unit.
