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.

The wiper blades can be cleaned by using a stiff-bristle brush and warm, soapy water.

pg. 6:16 Service diagnosis

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".


Starter fails to operate (or operates very slowly)


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.


Loose or corroded battery cable terminals.
Check battery terminals and clamps. Clean or replace if necessary. Check that the starter cable is secure at its terminals.
The ground strap, which connects the body to the rear of the engine, should also be checked for corrosion or looseness.


Open circuit between starting (ignition) switch and starting (ignition) switch terminal on starter.
The circuit is closed if a clicking 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.


Starter motor defective.
If the above checks have been performed, and no fault is evident, the starter may be defective.
NOTE: In this case the headlight intensity will not decrease when the starter is engaged.

pg. 6:17 Service diagnosis (cont.)

Starter motor operated but engine does not start


Intake system leaking.
Check vacuum hose connections at manifold and idle air control valve.


No fuel reaching engine.
Check for fuel in the tank.
Check fuses No. 30 and 31.


No spark.
If there is no spark, check that the high tension lead from the coil to the distributor cap is connected and that the wires to the distributor and coil are connected.


Spark plugs high tension leads or distributor cap is wet or defective.
Clean the parts with a dry cloth or spray with a moisture remover. Replace defective or worn parts.


If no fault is found following the above steps, contact your Volvo dealer.


Excessive fuel consumption


Fuel lines leaking.
Check tightness.


Spark plugs worn.
Replace plugs.

pg. 6:18 Service diagnosis (cont.)

Erratic idle (misfiring)


Intake system leaking.
Check vacuum hose connections to manifold and idle air control valve.


Worn spark plugs.
Remove. Clean or replace spark plugs.


Engine stalls at irregular intervals


Defective wires.
Check wire terminals at: fuel pump, fuse No. 30 and 31, 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 line fuel 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 deposit on the spark plugs. If this procedure is not effective, clean or replace the spark plugs.
Please be aware that misfiring spark plugs can cause damage to the catalytic converter.

pg. 6:19 Shiftlock release


Shiftlock release


The gear selector is locked i the P position. To release the shift lock, the ignition must be ON (ignition key in position II) and the brake pedal depressed.

  • Depress the brake pedal
  • Move gear selector to desired position
  • Release the brake pedal
    If it is not possible to move the gear selector, check fuse 27
