turn signal problem

Hello , everyone

I got a promblem on my chevy c 1500 2 wheel drive.
the turn signals blow the fuse when i turn the key on. as of know i have take all the lights out the rear lights are not hooked up , the turn signal switch is unhook

at the turn signal flasher there are 3 wires
black that reads a ground
blue that goes to fuse panel
purple that goes to turn signal switch

when i test the wires at the fuse box one side is hot from ign. or side is gound that is the blue wire from flasher

when i unplug the flasher it is not hot on the blue wire in the panel
when i put a hot wire on the purple wire on the turn switch the turn signal will work not blink. so i think the promblems some where around the flasher.

does anyone know how to fix this or how to try to rewire a new flasher in. thank you.

i been reading that the flasher has a ground that makes it flash.

sounds like a dead short to me,
i would check for ground in any of the turn signal/brake wires going to the rear lights

if not the a short in the turn sig switch assembly or in the column

if yours is an 88-up these trucks are good for wiring shorts and plug corrosion

common place on these, have worked on many of these trucks with wiring issues especially with the lights

also ones with melted harness connectors

very common problem

pull a connector apart and the connector plastic around a spade connector in it is melted badly

its crazy

also, these later trucks are real good about sharing many different circuits on a fuse

for example the 4x4 control, dome, dash lights and so on share the same fuse

its a mess

good luck
