Do a bench test without removing headlights, just the electrical connectors, if it's fine, and you know for sure the new module was programmed correctly, just reset the module, you know it's the problem. If you have a scanner like foxwell nt510 elite, you should be able to reset it. If you used ids for programming you should also be able to reset the module with it.
