On to the next item on the 'to do' list

Wiper motor not working.
New motor, New 35 Amp fuse in #9 Main fuse box.
No power at the plug
Possible causes: a) faulty relay, b) faulty stalk switch

Researched fuses in both my Service Manual and Genuine Parts Catalogue.
Cannot seem to identify the relay for the wiper motor.
We think it it is either the red or black one mounted vertically under the black plastic cover behind the drivers side headlights.

Thanks in advance, again.

 

According to my S57 the relay is in the RH component panel behind the dash

 

Doug is right.
