Addendum: On the Opel Corsa there are no fuses responsible for the turn signals (indicators). Relays number 15 and 16 are responsible for their operation (they can also be made as one large relay, see below).
Relay box
The relay box (with BCM unit inside) is located next to the Battery (#2).
To access it, it is necessary:
- Unscrew the torx bolts and remove the plastic cover.

Additional interior Radio fuse
If you have problems with the radio and you have checked all the fuses under the hood, you should check another additional fuse on the back of the radio.
To access it, it is necessary:
- Disconnect and remove the stereo from the dashboard.
On the back of the radio there is an additional 5 Amp fuse.

 Corsa C (2000-2006) with their layout and assignment){kind=link}
2005 Corsa VN05 WZS has a different relay box arrangement, and I’m still looking for the horn relay!
If you send me an email address, i’ll post it to you.
Raymond Andrew Manson Smith, we answered your email, please check it.
P.S. The problem is solved
First of all, I would like to thank you very much for sharing this valuable information with us. My vehicle is Corsa 1.3 CDTI. The fuses I need for the newly purchased front fog lights are marked as numbers 41 and 42 in the fuse table. But I could not see the number and location information of the relevant relay. Thank you very much again in advance for your possible answer.
Hello, thank you very much for the review. The front fog light relay is located in the main fuse box under the hood – number R17. On our diagram it was an empty (reserve) place. But on models with fog lights it is there.
Perfect !! Thank you
👍
Thank you this has proved quite useful as I try to find the fault on my Vauxhall Corsa 2006 model. Unlocking passenger side door and now speedometer not working. Going to attempt to check the fuse first to see if this is the problem if not then the relay. Even the Corsa hand book never had a proper diagram indicating what fuse relates to what. Thank you once again. Bx
Thank you for your feedback! Happy to help! 🤝
How do you remove relay box cover how many screws are there and were are they
Trying desperately to figure out the issue with my side lights (park lights). They used to work fine. Now when I switch to park lights nothing happens. I’ve taken the switch out and checked that there is continuity between pins 1 and 5, so the switch appears to be fine. Also, the relays for the park lights are meant to be no. 18 and 20, but on my car there are NO relays in these positions. Not really sure which relay they’re going to if I don’t even have those relays (there have never been relays in these to slots).
Odd thing is that the side lights do come on when the switch is in the middle position and the switch for the interior light is pressed at the same time. Not really sure what else to check.
Thanks for the understanding you have pas to me
Thank you!
Hi there. Most useful I could find. Think Im all set apart from 2004 Corsa C 1.2L has battery warning light on all the time. Had new battery and alternator. Could it be the cooling fan/system Fuse No. 52 Large 30A? Thanks in advance
Hey Guys,
I’m looking for Glow plug relay fuse (if there is one) on opel corsa 1.7 dti (y17dt)
Thanks in advance
Which fuse is for altonator
I have a 2003 Corsa C that drains the battery after a few days. I just put in a new battery and decided to do an amperage check with everything turned off. It drains 0.7 amps and after a few second it goes down to 0.11 which is still way too much. I started pulling fuses one by one to see which circuit is the culprit. Both #1 and #3 seem to be involved. I can also hear a relay click when I hook up the ground through my multimeter. I was hoping it would be the radio so I could just leave the fuse out but #1 and #3 seem to control some important functions. Can anyone suggest what to do next?
