My trunk wont shut on my 1991 buick park ave. Is the bottom part of the latch supossed to be at an angle?

I believe this is the part you will need to replace, but you should confirm before purchasing replacement.

you might try lubricating the trunk latch with a silicone spray or wd-40 and unlocking it with the key while it is open. There is a chance there is a small broken spring in the latch that is not pulling it over to full unlock position and when you tried to shut the trunk it is actually already in the locked position.

{wmstalk} I'm looking for the fuse for the trunk for a 94 park ave my trunk lid won't shut and I believe its the fuse I show I have no power to the trunk.If you could please help me and let me know witch fuse box that would be would be a great help thanks!!!

Call a lock smith. Your insurance will most likely pay for lockout service. Your other choice is to pry the lock out, and then use a large screwdriver to turn the latch, which will open the trunk.
I'd go with the first option!

There is a motor on the bottom latch that goes bad. Make sure that the fuses are all good. They can be found on the driver's side left of steering column. On the cover if you flip it over will have a list of the fuses and what they go too. If they are all good, the motor is most likely at fault.

The latch on the deck lid needs to be clicked open so it can catch the striker. Try key to unlock and see if you can get the latch hook open.

May have to take the panel from the inside get some oil on the componet.

sounds like the latch on the trunk door is stuck open try to lube with wd40 , if wont work needs replaced hope this helps
