The colour code in manual appears to bear little relation to the five wires going to the motor, but the White/black wire appears to be the earth and the connection is good. Power i'm presuming is ok as the headlamp motors appear to be from a commom fuse.
Part of the problem is I don't fully understand the wiring diagram - ie what should be happening when. Any suggestions or experience of common faults? (89SE).
Suppose it could be the motor itself but it was working perfectly a few days ago and I don't want to be changing a part without some faith its faulty.
Any advise appreciated
