Read on another site, to simply lubricate the latch excessively with WD40 and then continue to open and close door handle until the latch releases and catches. I just tried this minutes ago with my Pontiac sunfire and sat in my car held the door closed and pulled the open & close door handle in and out until the latch caught. It worked great !! Now the door latch catchs without a problem. Apparently, some latchs just need to be lubricated quite often. Hope this helps.
