Turn signals I have a 1998 Buick Century. The rear turn signal flashers were flashing fast but the front signals were not flashing. I checked the left front and the socket and bulb were burnt. Upon cleaning them it started working properly. When I checked and cleaned the right side the turn signals stopped working. Since the flashers were still working when I attempted to clean it I thought I had blown a fuse. I checked all the fuses on the passenger side with a test light, paying special attention to the one marked "turn signals". All fuses checked good. Can you please give me some idea as to what happened here. Thanks

I dealt with a similar problem on an 01 Alero (very similar car) and found that the wire that grounds the signal filament of the bulb was broken inside the harness. I tapped into it and grounded it to the chassis and resolved the problem. It's no guarantee but if you have a multimeter, check each wire's continuity to ground as well as the impedance between each of the wires on the harness, on both front signals (for comparison purposes), and it'll show you if you have a problem such as the one I dealt with.
