Where is the signal flasher in a Vauxhall corsa?

it is under a black plastic cover at the right side of the car as you look under the bonnet. it is right at the rear you undo about 5 screws, which hold the cover in place. to do this you will have to undo the bolt securing the battery and without taking the battery off move the battery to the side so you can get your screwdriver in behind the battery. once you have managed this, pull off the cover you will see either two separate relays near the front or one large one ( usually yellow in colour ). I hope this is of use to you...................... Alan
