Buick Repair Questions? Ask a Mechanic for Answers ASAP
if you can hear it clicking still then the Front Seat Recliner Actuator Motor assembly has failed, likely sit little drive line piece has failed, GM service these as the seat back frame assembly, if you pull your seat back cover off you can look and see whats clicking but GM won't carry service pieces for it because they don't want them timed wrong. Let me know if you are doing it yourself I can get you some directions.

if you get the rear cover off you may be able to run it by hand you will probably have to do left and right individually so do each a little at a time so it doesn't bind up. I have been able to cinch a drill on the little drive cable at the motor on some but i haven't done it to a recline one but i assume you could.
