I've got a 2004 Pontiac Grand Am and the right turn signal is blinking fast. I have replaced all the bulbs thinking that would fix the problem but it is still blinking fast

Fast blink = burned out bulb

Could be a number of things but it sounds like a turn signal switch is starting to go bad. That or another bulb is out or going out.

when turn signal blink faster means there a bulb burn front or rear of car

http://www.wikihow.com/Fix-Grand-Am-Turn-Signals You can try this , if you don't want to fool with it, spend $40-$50 and replace multi-funtion switch

Bad connection or ground

you would need to buy a blinker relay

Verify all front & rear bulbs are working the same as the right front. It blinks fast usually because bulbs are burnt out or flasher is bad.

Check all the bulbs in the faulty side (front and rear), one of them must be the wrong type for application. Different blinking speed is the way of the system to tell you that something is not right. It only stops blinking if the bulb is burned out. I have seen that the most common problem is in the rear lights, using a stop light bulb ( two contacts) in the turn signal socket.

you have a bad turn signal multifunction switch in the steering column.

Usually a fast turn signal means that there is a light out. You should probably check all of your lights, including back-up lights, and turn signals. If there is one out then replacing the burnt out bulb should fix the problem.
