no help for DIY, but I mentioned this (lock pin does not rise, door won't open outside) at my last service and my beloved mechanic at the 'stealer' said 'ayep' and sprayed,tweaked.whutever and the problem has not returned (no parts, only labor)

my pass rear reg failed on the -Drive Home- from purchase, so it's already been cranky in there, but I am assured not from damage, etc. (only two regs replaced ~125KMi lifetime, here).. I empathize, but it appears there is a PM (didn't think to ask)

suggest changing topic title to rear passenger door LOCK? tia

I can no longer hear the problems of doors.
This month is replacing the lock on the front left, front right, and behind the left is starting to fail.
Three locks in one month, I´m crazy....whith the car !!!!

I did not understand much of what you replied, could you please clarify on how yr problem was solved by the stealer. Where di he spray and since my doors cannot open at the moment , i dont know where to start from.

Thanks.

again, I didn't think to ask as it takes a bit to find out if the problem returns - it has not in my case, so apparently the stealer does have a preventative maintenance fix.
