The passenger front door will not lock on my 98 V70 T5, either with the key, the power lock buttons on both front doors, or by pressing the plunger down on the door itself. In all cases the plunger goes up and down properly, the door just doesn't lock. I've seen many postings on the site about power lock problems, and many refer to volvospeed.com's Red Evil Plast Lever (REPL) fix, but I'm not sure if this applies to my problem. Not to mention his repair description seems very involved and risky ($$$$ if you break something) so I'd like to be sure that's my problem before I dive into it.
