SOURCE: How can I remove front row seat headrest?

Most volvo headrest can be removed by releasing the catches which are on the back of the headrest on some models and on the front on others I believe on 960 they are on the back. To release the seat on a 960 look where the shafts should be then follow it down on the back where the seat back top stops then goes in press around that area you should be able to find the catch there pull up on the headrest while releasing the catch you have to do this on both sides. The headrest should come off this also works on 740 and 760 series the volvo 780 is a different story the only way to get the headrest off on that is to disassemble the seat

Thank You ghost4548, we went back to the dealership and it was a small fuse problem. It was a tad awkward since we went back to the dealership to fix this problem 2 days after we went to the dealership to BUY this car!

Get out your voltmeter, unplug the connection to the seat's motor, underneath the seat, and hit the switch. if youve got power going to the motor then youll need to replace the motor. If not, it's probably the switch. Also make sure the wires are not cut or damaged somewhere between the switch and the seat.
