Trunk Latch

My trunk latch, the one above the rear license plate, gets stuck sometimes.
How do I lubricate it?

The car is a 2004 CLK320 Coupe.

It may actually be broken. You'll need to remove the carpeted paneling from inside the trunk lid to access it.

I am quite certain that it's not broken.

The normal way to open the trunk is to pull the latch towards me. Sometimes when I go to open the trunk, the latch is already in the "pulled" position. I have to push the lever to the "center" position and pull, this would unlock the trunk.

I think this latch has to be lubricated but I do not know how.

I think what Rudeney was trying to say is that he doesn't think the latch is "lubricatable". I would think the trunk latch has some type of spring mechanism that pulls the latch back after opening/pressing it.

By moving it back manually into place, you may be able to manually do this.

If the car is locked, are you still able to open your trunk? That may be a definitive way to see if the latch lock is broken.

Just checked. When the car is locked, I cannot open the trunk with the latch.

The latch works as expected most of the time. When the trunk is open, everytime I press on the latch, I can hear an electronic click.

I am hoping there is a way to lubricate it before it gets stuck permanently.

I suggest spraying some WD40. Pull back the carpeted area behind the latch assembly. Good Luck!!!

I went to my indie for other work and I asked hime abou tit.
He sprayed WD40 at each side (left and right) of the latch.
He said this happens often to a w209.
