To find the rear heated screen relay open the bonnet, and on the passenger side near the windscreen there is a plastic flap if you open it you will see a fuse block , If you look behind that box there is another enclosed box which houses seperate relays for the rear screen and the indicators. To get access to this box requires removal of the indicators and plastic scuttle below the windscreen.Once you have done this you need to remove four torx screews to open the casing to access the relays. To replace the plastic scuttle you need to re-seal it to the winscreen.
its on the passenger side of the engine compartment under the wiper pannel. its deep in becoz of the body design. you'l see a relay box then you have to identify it somehow

The location of the cooling fan relay on a Vauxhall Corsa is under the dash. It is in the relay box on the driver's side.
Pull it out, and plug a new one in.
Fuse box under the bonnet.
I believe the trip sensor (switch) is bolted to the rear of the fan housing which tells the fan or relay in circuit to power on once it is heated by the air temperature from the radiator/engine.
