Absolutely! Everyone likes working for you for free. I'm sure you like working for free too. You can expect to not be charged a second time if the mechanic made a mistake. That is part of the checks and balances of the "flat rate" system of billing labor charges. If the mechanic didn't do anything wrong it is up to the manufacturer of the part to warranty it, and some of them will help cover the time needed to replace it. When they do not, that is what the parts markup goes for that all businesses charge and what some people gripe about.
The shops that I worked at were very reputable, and they would typically not charge for labor when a new part failed, but there were always exceptions to the rule. You may be past the time limit which is typically 30 or 90 days for labor and whatever the manufacturer provides on their parts.
I can suggest that you won't get very far by demanding free service. Pretend YOU are the one being asked to redo your work at no charge and you'll know how the mechanic feels. If he didn't do anything wrong, the shop is going to pay him for his time, which he deserves, even if they can't or don't want to charge you again. Before you start demanding anything, give the shop folks a chance to at least offer to fix the vehicle for free. They're human and they're going to respond to demands the same way you would.
