Hi there Chris, and welcome to the Owners Forum. I hope you find us a helpful lot!
You don't say in your post which Zafira you have or which internal system yours is fitted with.
The book lists several different kinds of Clock/Trip/ information systems as I list below....
1) Time Display in Odometer.
2) Triple Information Display.
3) Multi-Information Display.
4) Graphical Information Display.
In the Vauxhall chart for the Zafira fuses, there are several fuses associated with the infotainment systems, depending on which one you have fitted. They are in the fuse box located in the vehicle passenger compartment (down by the driver's right knee panel!) and are listed in the book as follows.....
Fuse Number 13 - 7.5A Anti-Theft alarm; information display; telephone.
Fuse Number 19 - 10A Radio; telematics; infotainment system.
Fuse Number 21 - 7.5A Ignition Lock; central locking; anti-theft alarm; radio; infotainment system.
Fuse Number 22 - 15A Hazards; information display; trip computer; infotainment system; control indicators.
Fuse Number 34 - 20A CD Changer; information display, radio; infotainment system.
Fuse Number 38 - 10A ABS; brake lamp; ESP; information display; cruise control.
That is the best I can do for you with the limited information you gave... Good Luck on the detective trail! Cheers... Robin
