My right passenger rear light won't work.

Asked by Sep 05, 2013 at 09:10 PM about the 2006 Chevrolet TrailBlazer LT

Question type: Maintenance & Repair

I changed all three of the light bulbs. My blinker light won't work right. I use my turning left
blinker and it works fine. I use my right blinker and it blinks at a fast pace. Do I need to
replace the board?

Try swapping the board with the left one temporarily, some of them have identical plugs, could be a bad connection somewhere causing it to think there is a burnt bulb, could be a fault in the board. If you don't know electrical to begin with I can't help diagnose it easily with you. Test the resistance of the board with an ohm meter is what I would do and compare the left to the right.

A rapid blinking signal signals a bad bulb. Does it flash rapidly on the dash indicator as well?

A rapid flashing light indicates an open in the wiring of the turn signals, yes 99.9% of the time it's a bad bulb but if changing the bulb didn't help then it's not that.

Btw, were you able to test it in any way?

no, my battery keeps going dead, and the key gets stuck.

yes the right turn signal on the dash is also fast.
