I have a '99 Integra GS and have been experiencing the same problem with my electronic hatch lock. I read a post by an Acura technician saying they always replaced the actuator assembly when they came across this problem. I assume he meant if the electronic lock is still working. I can still hear my lock working, so I'm probably going to order part # 74840-ST7-A01 (ACTUATOR ASSY.) from Sunnyside Acura (http://acuraparts247.com) sometime soon (item number 25 in the picture).
