Turn signals dont work

Did you check the light bulbs and the fuse? Sounds idiot simple, I know. But sometimes it's the simple stuff we forget to check, especially when we start overthinking the issues....

 

Did they work before you took the switch apart? Sounds like a flasher issue to me. By "lights stay frozen" I'm assuming you're meaning stay on with the switch.

 

I would agree.

 

flasher relay most likely

 

When the t-sig lamp comes on with the switch it means the switch is good and all wiring and circuits are also good. The switch gets power from the flasher so the flasher is doing that much but that's only half of it's job. The other half of the flashers job is to interrupt the circuit to cause the flash by being overloaded by the circuit (bulb load), so the flasher is the cause of your issue.

 

The flasher relay is in the fuse box. Largge black square looking thing, you can sometimes hear it "click" when the turnsignals are activated. Your fuse box cover should have a diagram on it to tell you what is what....

 

brsims it depends on the truck as to where the flasher is located.
