Hi all, I’ve searched endlessly to find a solution on the forums but have yet to. This is the problem I have:

2001 V70xc

left rear door lock will not unlock or lock in any way without manually pulling up or pushing down the ****. Also, when I hit the door lock/unlock button in the car it use to unlock and then lock and then unlock. Now it only locks, if I push it again it’s as if it try’s to relook all the doors. It never unlocks unless I use the fob. The fob is also intermittent if I use it then I have to wait a little while before I can use the fob again. The battery in the fob has been replaced and same symptoms with backup fob. All these are new issues that happened at or around the same time. Perhaps related? I replaced the left rear door lock actuator twice with used ebay ones thinking they may have been defective I then bought a new Volvo one. It too has not fixed the problem. Any advice would be appreciated. Would like the left rear door lock to work again. Thanks!
