Alsacristales Gol Country 1.9td 2005

Hello, a month ago I bought a country goal with the problem that the crystals did not work, the seller told me that it was a module that commands them that had burned and that he got it, the question is that when getting it and plugging it they still do not work. For my part, I already tried the engines and they all work, I hope someone can give me a orientation. Thank you.
