Turn signals wont work

It depends on the make , model an year vehicle an what controls that signal light . Lot's of vehicles use a BCM - body control module to turn on these light's an also sends a message to the radio for the sound . Sound could come from the driver door speaker or speaker inside the instrument cluster . Do you hear sound for the right turn signal ? Looking at a wiring diagram would show what's all involved in the turn signals for your vehicle. Free wiring diagrams here http://www.bbbind.com/tsb-wiring-diagrams-database/.

flasher/blinker is busted. this is located under your dash board. remove steering column cover, turn on LEFT turn signal (yes, the one that is working), then you will hear a clicking sound. locate the relay that causes the sound. there you can see 2 relays (one for LEFT, other one for RIGHT turn),replace busted one.

check your fuse for your signal.

yes but first check the bulb

the light in th DASH-BOARD IS out, if you hear clicking & outside is click-g,theres not a fuse,for signals, there is a flasher-relay chk under dash or by th kick-panel or next to FUSE-CLUSTER(BOX), HOPE this helps, good-luck...

you are describing a typical turn signal switch problem, all those systems run through this switch, its about a 110 dollar part

Replace the turn signal switch. Bad contact inside causing a crossing of the circuits. When the turn signal is applied it should open the brake light circuit allowing for just the signal to work. Doesn't sound like the switch is doing it's job.

sounds like a turn signal switch on the column

Rear lights are double filament bulbs one side for the lights other side for the brake/turn signals so it still may be a bulb. Do u have a test light or volt meter you can check to make sure u have power there when brakes or turn signals are activated. Or just try another bulb.

I'd get a 12vdc test light if you don't have one already & start from plug, and keep probing back from there. It may be as simple as a bad connection under truck where joined into harness.
