2000 Chevy C3500 Dually turn sig/brake light

MiamiHost · 02-11-2008, 06:15 PM

Hello All

nice spot on the www you have here

I search the forums didnt really find anything leading to a fix for my issue..

all lights on truck worked fine until tonight, was driving home and notice that the "left" turn signal was flashing like 3 times faster then normal.. got home and checked for any bulbs out... rear turn/brake light not working..

ok.. went to local parts shop.. got replacemts bulbs.. replaced what I thought was bad bulbs... still not turn/brake light on the rear driver side

front turn sig works fine, all right side works fine

this truck has the board type bulbs

suggestions

Thanks

fast signal means probly an open in the wiring somewere, check with test light before and after board on tailight, then work your way forward is there any modified wiring underneath for trailering? check everywere it doesn`t look factory most likley place for faults is were people have changed things

I had this same problem on my 99 suburban, it turned out to be the plug that was teed into the tailights for the trailer wiring, just a bad connection.
