Volvo remove lumbar support knob - 2000 Volvo S80

Most have a recessed allen screw, or star-key nut located on the back side of the knob...some are hidden by a clip on cover...look for at the base of the knob design...

there is either an attachment screw maybe under a plastic cover or a retention clip behind knob to hold it on

IPD, just search IPD Volvo in Portland Oregon.

There are several problems that could exist. Firstly I would check the fuses. If all are good, either the knob has quit working, or the motor that increases and decreases the support has gone out. If you can find the positive and negative wires going from the wheel to the motor, you can test it with a voltometer. You would have to have a manual to identify the wires. But if you can, test to see if the knob is sending an electric signal to the motor in the seat. If there is a signal going through, the motor is out. If there is not a signal going out, the knob has probably gone out. Hope this helps.

Go to the junk yard and pull you another one.

there should be a clip behind the nob a half moon clip or screw in front

Need to replace the whole knob. Removel y pulling out the knob upright.

check the lumbar switch first it is an electrical switch and also vents the bag
