Ok, So I am having a weird problem going on with my blinkers all of a sudden, Left and right blinker, I blew a fuse earlier today and my Left rear blinker would not work at all and the bulb blew, due to trailer Light malfunction, after replacing the fuse & the bulb, when i use the blinkers, either left or right It blinks really fast, When i put hte 4 way flashers on it is normal speed, all light bulbs are working. Ideas??

 

Yes,ideas. What was trailer light malfunction, that's just a bit vague. You could hit it two ways. Start trying to trace and see if there's a short in the trailer light or start replacing parts.
Its 50/50 the parts are cheap.

 

Its most likely a bad ground or a short in the wiring, look around under the bumper and trace the wiring til you find the ground and clean it, in the process make sure the wiring isnt damaged and there arent any shorts, signals blinking faster or slower than normal is directly related to how much resistance is in the circuit, if im not flip-flopped here, low resistance causes fast blinking, less bulbs on the circuit (burnt out or incorrect bulbs) or a short would cause that, on the other hand, more bulbs on the circuit adds resistance, such as a trailer hooked up, usually causes slower flashing, or a bad ground will add resistance just the same. Usually bad grounds wont flash at all.
Also have to ask, you arent running LEDs are you?

Hope this helps and hopefully i didnt mix that all up, been a while since ive dealt with a flasher/lighting issue.

 

It does it even with the trailer Not even hooked up now. All the lights are working on the trailer, Brake/Blinkers etc. Just all the blinkers Left and right when its not on 4 way flashers they flash really fast, all bulbs are good, checked all grounds, I even replaced a fuse underneath the hood that was for left turn signal...ALl the blinkers when on 4 way blink normal speed, but when using left or right its fast....WIth or without the trailer attached....Is it possible the combination flasher under the glove box could of burned out perhaps??

 

Yea, do you have three flasher solenoids under there, like six bucks apiece you can try switching them around in some kind of organized fashion. Mark them with a sharpie.
You would not believe how simple it is to confuse three things. Ever see the "shell game"

 

I only found one flasher under the glove box
