Mine did the same except it was the left turn signal. After nearly hitting a motorcycle who turned left in front of me because he thought I was turning left I went to Napa and got new springs. Was under $3.00, just ask for GM turn signal springs. Yank your wheel off and replace them. I never did it before and it took me about an hour and half.
