If an electrical component fails to function, it is likely that a fuse has blown due to a temporary circuit overload.
The fuse box is located in the engine compartment (see illustration) and can be opened by lifting the cover.
A label on the inside of the cover indicates the amperage and the electrical components that are connected to each fuse.
The easiest way to see if a fuse is blown is to remove it. Pull the fuse straight out. From the side, examine the curved metal wire to see if it is broken. If so, put in a new fuse of the same color and amperage (written on the fuse). Spare fuses are stored in a compartment in the fuse box.
If fuses burn out repeatedly, have the electrical system tested at a Volvo retailer.
If you find it difficult to remove a fuse, you will find a special fuse tool clipped in the fuse box.

Replacing wiper blades
Lift the wiper arm off the windshield and hold blade at right angles to arm. Pinch the end of the plastic clip located at the back of the arm.
Slide the wiper blade along the arm to release it from the hook.
Install new blade (installation is the reverse of removal) and make sure that it is properly attached to the wiper arm.
For reasons of safety, you should change the windshield wiper blades as soon as they start to leave marks on the windshield or fail to wipe efficiently and cleanly.
|To obtain maximum lifetime from a set of wiper blades, clean them with a stiff-bristle brush and warm, soapy water as part of a normal car wash.|
Replacing headlight wiper blades (certain models)
Pull the wiper blade in the direction indicated by the arrow in illustration to remove it. Press the new blade into place. Check that the new blade is properly attached to the wiper arm.
The diagnoses outlined below are intended to serve only as guides to locate and temporarily correct minor faults. Causes of unsatisfactory performance should be investigated and corrected by your Volvo dealer only. See section "Road Assistance".
Engine fails to start or is difficult to start.
The instructions for starting the engine have not been followed, see page 4:5.
Start the engine according to the instructions.
Weak battery or dead cell
With the starting (ignition) switch in the "Driving" or "On" position, check to see if the warning lights on the dashboard come on and if they stay on when the starter is engaged. if the lights do not come on or if they go off when the starter is engaged the battery is discharged, or see below.
Fault in the electrical/distributor ignition system
Check all the electrical connections to the starter motor and battery.
Clean or replace battery terminals if necessary.
The ground strap should also be checked for looseness or corrosion.
Check the spark plugs (gap should be 0.7 mm), clean or replace if necessary.
No fuel reaching engine
Check that there is fuel in the tank.
Check that none of the hoses/connections in the fuel system are loose or kinked.
Check that the fuel pump fuse (no. 2) is not blown.
Open circuit between starting (ignition) switch and starting (ignition) switch terminal on starter
The circuit is closed if a ticking sound is heard from the starter when it is engaged. If no clicking sound is heard, check that the blue wire at the starter is secure. If still no clicking sound is heard, the starting, (ignition) switch or the wire is defective.
Blocked air cleaner/fuel filter
Imbalance, resonance, or heavy steering during driving
Have the wheels re-balanced.
Insufficient oil in power steering pump
Check the oil level, see page 8:12.
Radiator hoses cracked or leaking
Check the radiator hoses and replace if necessary
Check the coolant level and add as necessary. See page 8:16
Fault in electric cooling fan
Check that the electric cooling fan functions properly.
WARNING! The electric cooling fan may start or continue to operate (for up to 6 minutes) after the engine has been switched off.
pg. 6:17 Service diagnosis (cont.)
Excessive fuel consumption
Spark plugs worn.
Erratic idle (misfiring)
Intake system leaking.
Check vacuum hose connections to manifold and idle air control valve.
Worn spark plugs.
Remove. Clean or replace plugs if necessary.
Engine stops running at irregular intervals
Check terminals at: fuel pump, coil, ignition switch and relays.
Intake system leaking.
Check vacuum hose connections at manifold and idle air control valve.
Fuel filter clogged.
Clean fuel tank filter and replace fuel line filter.
Misfiring at highway driving speed
Spark plugs fouled.
Drive the vehicle in a lower gear and keep the engine rpm higher for a few miles in order to remove carbon deposits on the spark plugs. If this procedure in not effective, clean or replace the spark plugs. Please be aware that faulty plugs can damage the three-way catalytic converter.
Fuel filler flap does not open
Faulty motor in fuel filler flap-
Open the cover panel on the right tail light unit and pull on the hook. The filler flap can then be opened.
Remove the right floor cover (the center storage compartment must be opened first) and the cover panel on the right lower tail light. Pull on the hook and the filler flap can then be opened.
pg. 6:18 Service diagnosis (cont.)
Electrically operated sun roof cannot be closed
No current to sun roof motor
The overload circuit breaker (no. 37 in fuse box) has been activated. Wait approx. 20 seconds for the circuit breaker to cool down.
Check fuse no. 35.
Shiftlock release (automatic transmission only)
The gear selector is locked in the (P)ark position. To manually release the shiftlock, turn the starting (ignition) key to position I and press firmly on the "SHIFTLOCK OVERRIDE" button located to the right of the base of the gear selector. While holding the override button down, press the button on the front of the gear selector and move the selector from the ( P )ark position.
