I took my car to a carwash and a day later i realized that the passenger seat wont fold down no matter how hard i try to lift the lever. I thought it might be a spring but i have no idea how to get inside the seat. it is very annoying cause when people want to go to the backseat i have to get out everytime. any response would be appreciated. Thank you.

i also have a same problem
in my case i bought 4 tires frrom other guy...then i put that on back seat
after that is didnt work...
good luck with ur car...^^

There is a cable in the seat that goes from the handle to both sides.One side usually breaks and won't let the seat fold.

Does anyone know how i can get into the seat and fix cause im sure that volvo will charge a lot to find the problem then try to do it. I am a pretty good do it urselfer so if someone can just give me a direction on how to get to it i appreciate it greatly. Thanks

Feel at the bottom of the seat.You will feel metal rings you need to cut them to open the seat.
Cut the ones at the bottom then there is more in the front of the seat.Cut them and lift the seat cover up little by little.
