2005 chevy colorado whole frnt left side lights

There isn't one. The function is done by the Body Control Module (BCM) along with lots of other functions.

Where is the turn signal relay on a 2006 Chevy Colorado?
The turn signal is controlled by the BCM (Body Control Module) that is located at the passenger side kick panel.

Fast flashing dash signals mean there is a bulb issue-DEFINATELY!

A dead bulb could do it.
Try the hazard lights to determine

bad bulb on right side check and replace

Sounds like your tail light board may be shorted,switch the board to the other side to see if the problem follows the board or stays on that side if so it could be a faulty turn signal switch.

I have this exact same issue with my 05 Colorado and its so annyoying (not to mention unsafe)... I thought it was just the blub- becuase in my case my signal is no loger blinking. My break light still works, as does my parking light...

Any thoughts as to why this is happening?

Please HELP!!!

If you put the tail gate down, there is 2 screw (phillips) that holds the tail light in place. Remove them & you can twist the bulb out. Thats it, put back together in reverse. Hope this helps.

On the truck, are the turn signals and the brake lights using the same bulb, if the brake lights are using a different bulb the trailer might not work withe the truck if it only has a 4 wire plug, might have to add brake lights to the trailer and use a 5 wire plug, yes this means rewiring the trailer and adding lights
