ford escort wiring diagrm

i have a u.k ford escort. my blower stopped workin. i changed the switch in the dashboard and now think it might be the relay. i dont have a wiring diagram. can any one help as its really cold now!
I don’t have anything on the UK Escort, but if it’s anything like its north American cousin have a look at the blower motor resistor. You should find it in the heaters air box under the dash, also the main connection at the motor itself is known for burning causing a bad connection.

Here’s what a generic resistor looks like, yours may not look exactly the same but close.
