<!-- from fixya rte -->Instrument panel stoped working - 2003 Volvo XC90

check the fuse for the instrument panel It may be blown.

there is 1 or 2 problems you have. there is a common problem with the instrument clusters going bad,and replaceing it can solve the problem. the other is that there is a body control module behind the fuse box under the dash,and it controls the instrument cluster

my car is denaly xl 2003 ,I stoped it with good condetion but when I came and try to start I foun not working I not remot not open the doors also I noticed not remember my infomation.I need your support to rectify this problem.

Instrument panel problem--possibly loose connection or poor ground--also have park light switch tested--may be worn out.

if everthing has stoped working and u have checkd fuses it time for a new intrument panel...hope it helps

Double check that everything is reconnected properly

Checked Every fuse in the fuse box (no small task).This includes #4 - Power point Instrument Panel, #14 - Day time running lamps (auto lamps doesn't work nor does auto lock), #27 - ignition switch run feed, #35 - Instrument Cluster, #41 - Instrument Cluster, #42 - Delayed Accessory, #45 - Ignition switch run/start feed, #102 - Door locks body security module, #103 - Ignition switch, #110 - Ignition switch, & #116 - Ignition switch. But I also check all other ones as well, they all register OK. AC panel & radio work. Turn signals work. Mileage does not work, trip computer does. So, basically, everything works except auto head-lights, auto locks, and the dash cluster (no MPH, RPM, mileage display, Fuel, Temp, Tran Temp, and Oil Pressure).

It sounds like you have a faulty Instrument panel Cluster (IPC) Your local dealer will have to confirm this as independant shops don't have the scanner capabilities for this diagnostic procedure.
I hope this helps.
Thank You,
