i would say maybe a bulb or a flasher
Could be turn signal flasher Check bulbs Could be a problem in steering column
Could be a bad flasher or just a burned out bulb.
Could be ALL your bulbs but more likely to be the flasher relay.
Bulbs? Sockets? Steering column switch?
The problem could be that your flasher switch is going out. I had the same problem on my 99 blazer. It sounded like a bee buzzing in my dashboard. Had the switch replaced and problem was gone. Hope this helps.
Could be a bad flasher
I replace my flasher fuse.Now they light up but won't blink.
could be a problem with the sesor in the emergency brake. a bad connection there could cause the light to blink with the vibration of the car running On some cars, the brake warning light will blink if the parking brake is set, and you drive... it could be a failed parking brake switch, assuming the brake is not applied. It is supposed to blink to get your attention. One car that does this is the Mitsubishi Starion, there are probably some others, too.
You could have a short from the controlls to the fan
first check fuses then flasher unit if still no joy get out your multitester or take to the shop d.cop
If a 2000 Pontiac Grand Am shuts off while in drive, there could be a problem with the passlock sensor. There could also be an issue with the fuel pump.
Wrong bulbs installed? Defective or corroded sockets? Bad turn signal flasher?
