98 Century front signal keeps burning out

Hello, 1998 Buick Century. I replace the front turn signal bulbs and they are ok for a week and then burn out. I have cleaned the connector, bulg socket. What do you think I should check? Other electical issues for FYI : dash light out, windows slow, wipers stop in up position. Thanks

It is likly your directional switch
Not sure if the century had the switch at the lights that you can change.

Thanks. So you think there is a directional switch by the front turn sinal light? The back turn lights do not burn out

Only thing I can think of is, a circuit has lost it's ground and is somehow backfeeding to ground through the bulb......

I see a lot about checking the ground but don't really how to go about it. Is the ground just for this circut? Where would I start? Thanks again.
