What do you do when the electric hood on your Peugeot 205 CTI does not work and you need to find the relay for your horn and washer?

Kia ora. If it's any help I had same problem with the electro/hydraulic roof on my own CTI. Problem was oil pressure switch mounted on front of engine block on left as you look at engine from the front. Got a second hand one . Not hard to fit and problem solved. Sorry can't help with second part of your question. Neil
