Answered then above, get new relay. Pull up right side front carpet to expose the plastic foot cover(if not there get one at a yard). IIRC 10mm plastic socket needed then the relay is to the right and high. Most likely hard to get out, been there 25 years. Could flow some solder but get a new one. You must get a 560 SEC or SEL relay, not from a 420
