The wiper relay on a Clio 2004 is located on the right-hand side of the engine bay, near the top. It is a small black box with a green connector on the front.
Here are instructions for finding the wiper relay:
1. Open the bonnet of your Clio 2004 and remove the plastic cover over the engine bay.
2. Look on the right-hand side of the engine bay, near the top.
3. You should see a small black box with a green connector on the front.
4. This is the wiper relay.
If you need to replace the wiper relay:
1. Disconnect the green connector from the relay.
2. Press down on the retaining clips and pull the relay out of its socket.
3. Insert the new relay into the socket and push down until it clicks into place.
4. Reconnect the green connector.
Test the wiper relay to make sure it is working:
1. Turn on the ignition.
2. Move the wiper switch to the first position (intermittent wipe).
3. The wipers should come on and wipe the windscreen once every 3 seconds.
4. If the wipers do not come on, check the fuse for the wiper relay.
If the fuse is blown, replace it with a new fuse of the same amperage.
