Door latch stuck 99 V70 XC Topic is solved

Could it help ?

Unfortunately not. I ended up having to destroy the whole darn thing to get the door open, which was fine because the latch was no longer functional.

Pictures to follow...

As promised, a picture of the final result...

Took 2-3 hours, hammer, drill, prybar and some persistence. Tore the son of a gun apart. Special thanks to Abscate for the cheering on =)

Moral of the story, if you start having the door not always catch right, don't wait, replace.

The metal piece at the very bottom of the image is the failure point. It grabs onto the latch paw and usually is manipulated to allow it to drop down utilizing gravity. It didn't any longer...

You have developed anti-gravity device?

Yup. I typically shoot politicians with it before debates. Makes it a bit more fun while we watch the rapid decline of society =)

Sometimes, when you have no longer other way to proceed, may make your feel unable to be a straight mechanizer , but not. There's no other solution. When I see yours pictures, it's obvious it would finish this way. These mechanisms need love and "lubrification". Ours "girls" are sensitives ones... !

Well done !

We learned way too much about the driver door lock mechanism on the P80 during this session

The outside door handle pulls a lever which rotates along the front -back axis of the car. The pivot point rotates a series of cams which pivot in the left Right axis of the car. Locking is effected by engaging /disengaging these cams with the various lock controls, the last cam lifts a locking pawl which allows the door latch, a U shaped piece, to fall to the open position.

Interestingly enough, this means that locking th doors adds no more security to the door staying closed than unlocked doors in a collision.

The most inboard of the cams lifts the door latch pawl, this is the one in Robert DIYs video that you push on the lower part to lift the door latch cam

You can’t see the final door latch cam unless you have the door latch out in your hands and peek under the cover

In our case, the second to last door latch lift pawl had broken off from repeated slams , leaving the door latch pawl in place permanently

We were able to drill through the ABS and phenolic resin case and reach the last lock pawl and lift it with a screwdriver....in three hours

Pictures to come , including a “ where to drill “ template

You have to drill on the outer side of the plate to reach the lock pawl, lift with a screwdriver , then pull the door to open

New part $175 from Volvo web store

Short trip cars get lots of wear on the door mechanisms. On my old 240s, I went through many door handle pulls. This was a soft metal casting (zinc?) and was different for LH and RH. When I stopped driving the 240s, I had consumed most of my parts cars LH pulls.

One thing you can do to prolong life, slight pressure on the door while you pull the handle. This takes the tension off the U latch while the pawl releases.

After this experience, i\m going to up my silicone spray regime to quarterly from semi-annually

Adding to this. When you pull the door handle the latch is lifting the lock pawl allowing the U shaped latch you see in the door to rotate and the door to open. As things wear, I wonder if you put pressure on the lock pawl before the door opens, which would eventually break it. Putting pressure on the door in while you lift the lock pawl would help this.

My T5 is in this mode. If I yank on the door handle, I feel tension in the mechanism. If I put 5 lbs pressure in the door, it opens easily. Lubricating helps this, I use silicone spray.
