hello am a swedish 19 years old with a volvo 745 facelift where am having probloms with the trunk beacuas you cant open the trunk from the utside but you can do it from the inside with a bit push/kick in the back so can anyone please explain what is wrong and what can be the problom

 

sounds like the outside latch handle has failed or has become disconnected from the latch itself (usually there's a small rod from the handle to the latch mechanism). You'd have to remove the handle to inspect. Given the age of the car, your best solution for finding a replacement part would be to visit a breaker yard (ie a used auto parts / recycle yard) to see if they have some other compatible 745s.
