1999 Chev 2500HD - Blinkers only blink when brake is applied. As long as the brake pedal is pressed, blinkers blink, release the brake and they stop. Front, Rear, Left , Right, no difference.
Bought it used, and am slowly figuring out all the quirks.
Any pointers ?
Check your 4 way flashers swith. if that doesn't do it than change the flasher. you can switch the sig lights flasher with the 4 way flasher. good luck

Try replace the bulbs in the rear first, thne next is checking the brake switch to see if it may be shorted but guess it will be the turn signal switch harness is bad. The blinkers and brakes are on same wire most common problem is the turn signal switch harness goes bad. about $50.00 to fix if you have a puller and a compressor to compress spring in the center.
The cause of this is the turn signal switch, there are numerous posts about this problem.
