I am not sure the flasher and the code are related. However, I would suggest picking one of them and fix it and if it solves the others then that is great. If not then we move onto the next one.

As for the flasher, have you replaced it? The most common cause of the flasher to click is the failed relay itself.

However, I attached all the info below on how to test and diagnose this.

Please run through this material and let us know what questions you have. Thanks
