my abs light stays on, and my overdrive light blinks .

Dear mac101010-- The fact that you have several systems failing at once indicates to me that the problem you are having with your 1995 Lexus ES300 is with the gauges themselves. Unless you are a skilled mechanic, I would suggest having a professional look at your car. Ordinary laymen shouldn't get involved with what is probably an electrical problem. Good luck from Bovan.
