Opel Corsa C (2000-2006) has its main fuse and relay carrier under the bonnet, on the left beside the coolant expansion tank. Two different electrical layouts are documented: a 53-position main panel, commonly found on cars with ABS, and a 32-position alternative layout, including certain cars without ABS. These charts cannot be combined or renumbered. The fuse for the 12 V cigarette lighter differs with the panel.
All 137 original table entries in seven complete tables and four original diagrams/photos are preserved. The main 53-position source lists lighter F26 at 25 A, but other documented Corsa C variants specify different ratings at this position. Always inspect the fuse currently specified for the exact vehicle and do not increase 20 A protection to 25 A without factory confirmation.
Where is the Opel Corsa C fuse box?
Switch the ignition off, open the bonnet and look for the protected electrical box on the left near the coolant expansion tank. Release the clips and compare the fitted fuse number layout with the diagrams. A separate supplementary relay carrier may handle central locking, wipers and washers; its positions are not blade fuse numbers.
Main 53-position fuse box, commonly with ABS
In this source, lighter/12 V socket F26 (25 A in table), front wipers F23 (20 A), fuel-pump supply F9 (20 A) and relay R10, radio F12 (20 A), starter F8/F48, ABS F50 (40 A) and power steering F49 (50 A). Use the installed fuse’s confirmed current rating rather than the alternative ratings of a different vehicle.

Corsa C with ABS versus without ABS
Different panel types have different cigarette lighter, fuel pump and wiper positions. In the alternative 32-position panel, the lighter is F20 (20 A), the fuel pump F16 (20 A) and the front/rear washer and wiper circuit F13 (15 A). The no-ABS relay R11 must not be confused with R11 on the main 53-position relay diagram.
| Pozycja | Amperaż [A] | Chroniony obwód / funkcja |
|---|---|---|
| ABS panel | – | Main installation with ABS: lighter F26 (25 A in archived source; verify fitted rating), fuel pump F9 and relay R10, front wipers F23 (20 A) |
| No ABS panel | – | Alternative installation without ABS: lighter F20 (20 A), fuel pump F16 (20 A) and relay R11 on this panel, front wipers/washer F13 (15 A) |

Which fuse protects the cigarette lighter?
The main 53-position layout uses F26, with the specific installed rating requiring confirmation; the alternative no-ABS panel uses F20 (20 A).
Which fuse protects the front wipers?
F23 (20 A) in the main chart or F13 (15 A) in the alternative box.
Can I use the Corsa D diagram?
No. See the Opel Corsa D fuse chart for the next generation’s different fuse holders.
Never bypass fuse protection or increase its amperage to mask a fault.
