You have 2 choices. You can try to grab the cable through the grill, cut it then see if the wire can then be pulled to release the hood.
Another option is to go from underneath with big screwdriver to move the latch thus releasing the hood latch. Not sure if you can get access to it on this vehicle easily. try a flashlight and from under the car reach way up into the latch area.

the hood latch is out of adjustment loosen three bolts and pry latch up retighten bolts also check cable isnt stuck in the open position spray with lube

No good deed goes unpunished. It sounds like the secondary safety catch is bent and not going into it's opening. Look at where the pointy catches enter the front frame of the car and make sure they line up as you close the hood. If they do line up, it's possible that the catch that springs against the hood pin is frozen or stuck. Spray some penetrating oil into the latch mechanisms at the front frame of the car and also try pushing the release lever inside the car back into the closed position. Sometimes they get stuck in the open position.

SOUND LIKE YOUR HOOD LATCH IS STUCK IN THE RELEASE POSITION. YOU CAN DO TWO THINGS. REPLACE YOUR HOOD LATCH OR PUSH THE LATCH BACK INTO POSITION MANUALLY EVERYTIME YOU OPEN YOUR HOOD. IT'S EASY. FIRST CHECK YOUR HOOD RELEASE LEVER (DRIVER SIDE KICK PANEL)AND MAKE SURE IT'S MOVING FREELY. IF LEVER IS OK,GO TO YOUR HOOD LATCH. LOOK TO THE RIGHT OF THE LATCH (LOOK DOWN FROM THE TOP VIEW)AND YOU'LL SEE A SMALL METAL BAR WITH A SPRING PULLING DOWN ON IT(MIGHT NEED FLASH LIGHT TO SEE BAR AND SPRING). TAKE A FLATHEAD SCREWDRIVER AND PUSH DOWN ON THE METAL BAR WHERE SPRING CONNECT. THE BAR SURE MOVE ABOUT 1/4 INCH DOWN. CLOSE YOU HOOD AND YOU'RE DONE. YOU JUST HAVE TO PUSH THE BAR DOWN EVERYTIME YOU OPEN IT.

Have one person pull on the latch inside and the other person pull up on the hood (sometimes depending may have to use a thin screwdriver to pry up carefully not to chip the paint). Once open lube the hood latch under the hood with wd-40. Make sure the latch inside is still connected to the wire.

Three part solution,
1. Lube the hood locks (yes there are two) the one you manuver from the inside (make syre you get the WD40 inside the hole wire and the latch you flipp from the outside when you open the hood.
2. Make sure the return springs for both locks are not broken otherwise no amount of lubing will help.
3. Adjust the lock. Open hood, remove grill losen bolts for the locks slightly, adjust and make sure they engage and release properly, tighten locks again and reassemble.

Have had same problem on 1990 240 DL. Go underneath, tap ball at end of hood latch sideways with small hammer (take a good look at it --- you should be able to see which way it needs to go to clear). Once released clean and lubricate.

stretched or frozen... have helper bang on hood center front while you tug..once open lube abd grease all latch areas and cable end you see there...good luck
