Hello, i have a 1994 gmc jimmy s15 in great condition. I want to change the hazard or turn signal flasher to electonic. My issue is, i have replace every bulb with led, turn and hazard work fine but when i turn on the headlights, also led, no turn or hazard lights.
I understand th theory of operation but nee a schematic to move forward.


Any help is much obliged

 

there should be a flasher relay behind the glove box you have to pull it down and drop it all the way down. those flasher relays can be replaced with an LED compatible heavy duty one. they will flash slightly quicker but not as quick as psycho flash when a bulb is burned out.
