If you have gone through the above checklist(s), then here is some important information to provide-

How do you know the relay is not functioning properly? If there is simply no mechanical action happening, then it could just as well be an electrical problem as a programming problem.

Check the lights on the relay itself- Are they changing? What color are they?
The sidecar and dashboard also have indicator lights. Check those.

Also be sure to check the relay's fuse, just in case.

Finally, it is important to list all of the steps you have already taken, and what their result was.

If you determine it to be a code problem, then you should provide snippets of the relevant code. We cannot help troubleshoot code if we don't know what is there.
