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.

  • Disconnect and remove the stereo from the dashboard.

On the back of the radio there is an additional 5 Amp fuse.

  1. 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.

  2. 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.

  3. 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
