if you turn on the hazard lights do they blink just as fast as when you just use the turn signals?
the car has 2 flasher units. the hazard light flasher is next to the fuse box and the turn signal flasher is above the glove box.
if there are no LEDs in the system and both flashers are going off fast could be a possible short, most likely place is the front turn signal light buckets. you can test that by popping out the bulbs in the front one at a time and see if you get a slow down in the flashing.
that would pin point the issue.
now if the hazards are slow and the signals fast you could try swapping flashers and see if the signals slow down, that would pin point a issue with the new flasher unit.
i went through a couple flashers before i found the one i liked. there are many manufacturers and some are faster then others some are slower and some are extremely loud when they click. there are also electronic flasher conversions for leds compatibility.
just note: do you have an LED conversion in the instrument lights in the dash.
having LEDs in the turn signal flashers also changes the amp load and can speed up the flashing. so even if you do not have leds on the external lights you have to consider the internal lights.
flashers are usually bimetal that heats up and cools down making the lights flash on and off, a change in the load reducing heat will effect the flashing depending on the make of the flasher this can result in a speed up or slow down. some flashers are NC (normal closed) and some are NO (normal open) so for example a lower load on a NC will cause it to speed up but the same load on a NO will make it slow down.
Electricity is fun!
