I have a 2002 Chev Cavalier that had the same exact problem. I replaced the bulb harness (purchased from a chevy dealership for around $5) which was fairly easy to do. I have had zero problems with it since.

If new bulbs don't work, it is probably the harness that holds the bulb. I had to replace both on my car after fighting with the problem for over a year and not knowing.

Replace the bulb that stays on and doesn't blink, if that doesn't solve the problem, let me know.

the bulb is blown out. you need to change it. also if the bulb is not blown out or if the blinker still blink fast after you change the bulb then you have a ground problem. just remove that blinker light and check the ground wire on it. if you need to replace it and find a good groun on the car. you should be fine. this is all it is .

any increase in bink speed is direcly related to a bulb being burt out.
