hi evry1. i have neglegted old 97 auto cabriolet im trying to nurse back to health. got excellent advice b4 from this forum fixed caar saved a fortune so many thanx 2 all who advised me.

now i have a new problem because my lights have gone MAD! started when rear light died i thout was just a bulb but wasnt. last week had only sidelights and 1 rear fog. now high beam works but not dipped and fogs dont work at all. sum1 said try multiswitch . did this a few months ago when some lights stopped working and everything was fine. but was from a breakers so changed it agen 2day but made no difference. the old multiswitch looked quite corroded lots of copper dust. Replacing bulbs doesnt work and fuses all look ok.
Could this be a problem with the relays? how can i check relays and which ones are the lights?
