2001 D2 S8 left side lights not working
 

I just got my car back from having the water pump and timing belt done and now the left side lights don't work. The mechanic is a good friend of mine and we have checked everything possible. Fuses ok earth at connector ok. I can't fine a wiring diagram to see what else is in cct. Can anyone please help. Wiring diagram would be great.
Thanks in advance
