My truck has been making a continuously clicking sound, coming from the blinkers. I tried to check it but it was not my turn signal being on. I started the truck last night and the actual signal was blinking along with sound without the turn signal being turned.

All manufacturers have seen fit to replace the cheap, simple, and reliable thermal flashers with an unnecessarily-complicated electronic flasher, so now we see all kinds of unusual failures. Start by checking that the flasher is seated snugly in its socket. Next, replace it as a test. We normally do not approve of replacing random parts to diagnose a problem, but in this case, the flasher is the likely suspect. The next suspect would be the signal switch assembly, but we also have to consider two wires could be shorted together.

Also check that the hazard flasher switch is fully off.
