Hello. I have a 1990 ls400 first edition. My fuel gauge, mileage mot registering on my speedometer, the cigarette lighter and radio wont work either. Someone told me it was a certain relay needing repayment. Would stone please help me and explain why its not working properly and possibly give me directions on how to go about repairing this myself? If possible could someone send me a YouTube link on how to repair this, if anyone knows of one
Thank u in advance. Frank
