I have a 99 chevrolet blazer 4wd. It's got about 130miles on it. When I use my right side blinker it makes a really rapid blinking sound and only in the front side the light blinks, the rear does not flash on the right side. The left side blinker is fine for both front and back. Any clues on to what this could be and how much it's going to cost me?

Burned out lights probably. If so, $10 at most for new bulbs.

If not it could be a bad ground or light socket or wire problem somewhere.

 

Okay. I didn't think it was the bulb because the brake lights work and it seems that they use the same light bulb? I did have a Uhaul place mess with the electrical back there to install a wire harness in order for lights to work on the trailer that was hooked up to my vehicle. Now that I think about it I do recall that the right blinker did not work on the trailer but the left did so maybe they messed something up.

 

It's either the light in the blinker or a taillight bulb out, check them all. It's super simple to fix and usually very obvious which bulb (and some times bulbS) need to be replaced.

 

Ok, yeah if the brake light works on that side then it's a wiring issue.

 

did you check the blinker fluid? Lol JK

if both brake lights work then there is an electrical issue somewhere. Id start by the trailer plug if you have one.

 

Gio we've been over this 1000x, blinker fluid doesn't go bad.

 

it does leak tho

 

Fixed! It was the bulb. Thanks guys for your input.

 

Glad its all fixed

Make sure you check your blinker fluid... This is why bulbs burn due to the blinker fluid not cooling the bulb off.
