1999 Buick Regal My husband borrowed this car from his dad. It had been having some problems before, and while he was using it the car just shut off while he was driving. He was able to restart it several times after it kept shutting down, and oddly it seemed to be every time he would use the blinkers. Now it won't even start, and every time he tries, the whole car makes a terrible noise and all the lights inside start blinking and flashing wildly, and it won't start. What would cause this, and how would it be fixed?
KK: Well, with that many things going on, it leads me to believe they may all be related. Sounds like an electrical problem for sure. The basics- check the battery connections carefully. Make sure they are clean and tight. Make sure the positive or negative lug is not about to fall out of the battery by grabbing hold of the cable at the battery and try to pull it out. The lug may also twist out when trying to tighten the bolt, or you may notice acid leaking.
Could also have a ground problem. Follow the negative cable down to the lower front portion of the engine block and make sure the bolt is tight. Have also seen a few engine wiring harnesses rub through on the bottom of the a/c accumulator (dr. Front of car, next to coolant fan -aluminum tank with 2 a/c lines attached) causing several different electrical problems. Check these things and let me know.
1995 Buick regal limited. COLLING FAN PASSENGER SIDE DOES NOT COME ON WHEN ENGINE GETS TO TEMP,RELAYS OKAY,FUSES OKAY,RUN HOT WIRE TO FAN KICKED ON SO FAN OKAY ANY IDEAS?
Answer: That fan is the secondary fan. It only comes on when the temperature gets to a second level of hot. The first fan comes on at about 225 degrees, the secondary won't come on until 250 or so. If it is running that hot, and still won't come on, you will need a schematic to trace down the problem. You have a wiring problem to one of the relays that control the system.
