Try this site. Very helpful and knowledgeable bunch of guys.
The link is to a search I did, (which seems to indicate a relay fault) but if all else fails, just post up a question on the forum.
Had the same problem with same car (95). Funnily enough it went away after a while by itself. I had forgotten about it until you mentioned it. Know the main dealer and he told me it was'nt worth the expense of an investigation.
