Hey Manuel - welcome to the forums! I've attached a diy tech article from our site that I think should be helpful to you - it's for the front window regulator (we also have one for the rear window too) - check out the steps and then post a Comment just below the article and someone will get back to you with details - I'm sure that it can be done and you're not the first to inquire. Best of luck and let us know if there's anything that we can help you with.
