As I don't carry my manual around with me,I can't be specific,but all the relays & fuses are under the dashboard in the passenger footwell,one set above the other at the side of the bonnet release,there being a clear plastic hinged cover over the fuses.These old style torpedo fuses can get loose in the copper contacts,the fuse metal(brass or aluminium) gets oxidised at the contact points at the bullet ends and gives a poor connection-you have to bend the contacts a little to get a good grip.Also water can drip on the relays & fuses from the battery compartment if the little rubber drain hoses & their flaps are blocked by detritus.
