you would need to check for voltage past the flasher unit and before the flasher make sure the problem is not the switch, or the wiring after the flasher.
replace the flasher fuse
Some vehicles has a flasher relay for the turn signals and another one for the hazard lights. Are you sure you replaced the correct one?
Maybe a short somewhere...did you replace the flasher unit? No - it was blinking spuradically(?) - now I have to blink it manually and it won't blink at all with lights on.
You have to start by checking the bulbs or the flasher I think it may be the flasher.>>>>>>>>>>>>>
you need to change the flasher can for the signal lights
try a new hazard switch. the power runs through this switch, and sounds as if it is burnt. Good luck.
That bulb is burnt out. When the circuit is not completed like with a blown bulb, the flasher unit will blink faster to let the driver know something is wrong with that side. It should only be faster with the side that is burnt out.
Buy a "highway" turn signal flasher
It has been my experience that when the blinker comes on but the lights don't blink there is one or more bulbs burned out. If that is not the case check the flasher.
change the bulb
The problem could be in you flasher located on the fuse block . or the multifunction switch located on the steering column.
You either have a bulb burnt out or the turn signal flasher is bad.
