All electrical functions and components are protected by a number of fuses in order to protect the car's electrical system from damage by short circuiting or overloading.
If an electrical component or function does not work, it may be because the component's fuse was temporarily overloaded and failed. If the same fuse fails repeatedly then there is a fault in the circuit. Volvo recommends that you visit an authorised Volvo workshop for checking.
Look in the fuse diagram to locate the fuse.
Pull out the fuse and check from the side to see whether the curved wire has blown.
If this is the case, replace it with a new fuse of the same colour and amperage.
Never use a foreign object or a fuse with an amperage higher than that specified when replacing a fuse. This could cause significant damage to the electrical system and possibly lead to fire.
