so i have a 2000 trailblazer and when i put the turn signals on when the lights are off the front corner light and parking light blink at the same time, but when my lights are on they alternate (corner light blinks on off beat).. and also the right blinks faster then the left.

 

They should alternate when the lights are on. When the lights are off, they will both blink at the same time.

 

ok thanks a lot. i wasnt sure

 

Glad to help!

 

If you have one side flashing faster than the other you might need a NEW flasher.

 

ok thanks

 

My TrailBlazer does the same thing.

 

young murph, if one side flashes faster than the other, it's usually 'cause a bulb is burned out. check with the lights on, as i've seen a burned out running light cause a problem with the signal part of the buld (could be shorting out inside the bulb).

a flasher knows no difference between the left side of your truck, and the right side. it only affects how fast (or slow, if it's acting up) the cycle will be.

 

yeah all the bulbs are fine, thats the first thing i checked so maybe its a short but no blown fuses..

and also all my lights flicker (head lights, dash lights, interior lights) i think its a ground but idk. any ideas

 

yeah, start cleaning/checking the grounds-starting @ the battery and working back from there. obviously check the wires for damage as you go along too.
