Turn signals and hazzard lights do not work anymore on my hyundai accent 2002

P1586 HYUNDAI - MT/AT Encoding Signal Malfunction https://www.autocodes.com/p1586_hyundai.html

The gm line of that erra runs their turn signal through the hazzard switch, when your turn signals are inop, try depressing the hazzard switch a few cycles, if this alows your turn signal to function again as hazard switch will be required to repair the problem, hope this helps

are the brake lights working? could be a fuse

sounds like your Idle air control Valve

Get a schematic and trace out the power source to those devices not working.

okay,the bulbs are amber for the turn signals.
the parking lights actuate by turning off the ignition and moving the indicator arm left.right.(not all markets)

I think there are 2 fuses for those switches. Fuse #11 & #39

Hope that works for you

check battery voltage,check all leads are clean
