my flashers on my blazer are "hyperflashing", I quote because that's what I found is what it's called.

I've been told multiple things on what the issue could be, but I want a second opinion from other blazer owners, I've been told they are flashing fast because a bulb is going out, I've been told also that it's an issue with my wiring somewhere.
I changed my flasher bulb on the passenger side and it didnt make a difference, i went to try to change the same bulb on my drivers side, but a part of my frame sticks farther forward on the driver front than on the passenger, making it impossible to remove the bulb.

should i try changing all the flasher bulbs to make it stop?
I recently replaced my flasher relay and it and it didn't do anything but make it so my flashers actually show on the instrument panel when prompted.
should I try and find a chilton Manual to figure out the wiring?
any help with my issue would be appreciated greatly

 

This is a bit of a stab in the dark, but this is what comes to mind to me.

In older cars, which I guess our Blazers now are, the resistive load of the incandescent bulbs will affect the rate at which the flasher turns the bulbs on and off. If I remember correctly, a consequence is that the flash rate will go up when a bulb burns out.

So, a quick check to eliminate some easy to fix faults would be to see if any of your bulbs are out, although I'm guessing they are not burned out based on what you wrote. Second is to see if they are standard incandescent bulbs with a tungsten filament and not LED bulbs.

Only because they can cause lots of issues, I'll also suggest that you check the grounds for the bulbs for your turn signals.

Good Luck

only one of my bulbs is out, it's the farthest right bulb for my blinker, I will check that and see if changing it will fix it.
also how can I tell if a bulb is incandescent?

 

[QUOTE=Jaxsan;755063]Sorry, I forgot to mention how to tell the difference.

An incandescent bulb will have a short, tightly coiled wire inside the bulb. This is heated by the electrical current which causes it to glow.

An LED bulb can have many configurations. One type will have a small flat panel, a 2-3 mm square, that will glow. Some will consist of what look like several mini-bulbs. Inside of these will be little panels, less than 1mm by 1mm, that glow.


The LED is on the left. The incandescent is on the right.
