MONTE CARLO Door Latch - Need Help!

Dafuq?

It LOOKS like it's normal. But if it's not locking once it gets into the lock position, then either the linkage is bent/misadjusted not allowing it to latch, or the catch latch isn't snapping into place. Maybe a spring is broken that keeps the latch closed? It's been a good minute since I've messed with these. There's 4 position hook ups on this thing. 1) inside door handle on the open mouth side of the latch. 2) Top position is the locking pawl for the inside pull lock 3) outside locking rod connection from the key lock pawl (and also any linkage from power door lock plunger) and 4) the outside handle connection.

Unfortunately, there's no rebuilding these, at least not with backyard shop skills. In ANY event, it appears this little joker will have to come out.

If you want to buy new GM, it'll have to be 3rd party as it's been discontinued. Naturally.

Latest p/n for driver side, LH, is 16608235 (passenger or RH side is 16608234)

probably not adjusted right as a test disconect the outside door handle rod and then without closing the door see if the striker latches i would use a screwdriver

Been a while since I messed with these. First try some wd40. I just went through similar issue with a Ford Escort. Pulled everything out, soaked in solvent, then sprayed heavy with WD40. Now everything works as it should.

Make sure it is completely unlocked, you might have moved that lever without noticing.

i second the wd 40
