I HAVE A 1996 CHEVY S10 BLAZER. THE PROBLEM FIRST STARTED WHEN MY HUSBAND CHANGED THE HOSE ON THE WATER PUMP SINCE IT WAS LEAKING. AFTER THAT WE WENT TO START IT AND THE BUZZER FOR THE DOOR KEPT GOING OFF EVEN AFTER WE SHUT THE DOOR. THEN THE DASH LIGHTS WENT OUT. MY HUSBAND TRIED TO DRIVE IT TO WORK AND THE ALTERNATOR WENT OUT SO WE REPLACED IT. NOW IT WON'T HOLD A CHARGE. WE HAD TO JUMP IT ABOUT EVERY 1/4 MILE TO GET IT HOME. THE VOLTAGE METER, THE SPEDOMETER AND THE ALERT LIGHTS ON DASH ARE NOT WORKING BUT ALL OTHER LIGHTS WORK. ANY IDEAS?
