probably a overstretched cable pull, or defective latch, i had the same problem with my truck. pull hood relese a couple times, and go to hood, give it a love tap with your fist abouve the latch ontop of the hood, if that dont work, you will have to go underneath your volvo and release it by hand with a screwdriver, try and lift the latch over the catch

THE CABLE HAS STRETHED OR AN HOOD CABLE NEEDS ADJUSTMENT OR HAVE AN ASSISTANT PUSH DOWN THE HOOD AND PULL UP LATCH AND SHOULD BE OK

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.

Not for sure on yours, but take a look were the hood comes down on the corners and see if you have a couple of rubber stops that the hood rests on. If so you can try and adjust the one on the side that is giving you trouble so the hood won't have so much tenssion on it. From your description, it sounds as if you have two hood latches? I can't imagine that- but thats the only way for one side to stick and not the other. If so you may also need to adjust the slack out of the cable to that one side also.
