I have a 2000 Impala. When I got the car it seemed to have electrical problems. One issues I%27m worried about is that my blinkers will stop working out of nowhere. When I would put on the signal%2C the arrows on the dash wont respond at all. It would happen on and off when I first got it%2C I would just turn the car off and back on and they would work. A few months went by without a problem%2C then about a week ago it started happening again. They will just stop when I am driving%2C and sometime restarting my car wont help. I%27m not sure what it is%2C or what it will cost to fix.

I'd buy a NEW battery....the electricals have gone wonky because the old one isn't charging up properly [car batteries lose their ability to accept a charge 10%/year], Because it has lived many battery lives by now is the time to replace this one again...and don't forget the black wire and the connection to the chassis at the other end and the connection to the motor....it is through clean power we can be sure components will behave themselves....and just for funzies could buy a new flasher unit and keep it in the glovebox for when this one goes bad~

I have three Impala's 01,02 and 03 they all have intermitent signal light issues. To fix the problem on all three on them I just need to wiggle the button for the four ways. It fixes them every time :-) All my kids have been taught the trick for fixing them.

All you need is a new Hazard switch for 55$ my car had the same thing happen
