Windscreen Wiper Linkage Push Rod Arms Repair

Product Information

Motor off:Three 10mm AF bolts passing through the motor plate into the motor housing are removed, and the motor can be detached from the mechanism and cleaned for refitting. Rarity:The new wiper linkage comes with new mounting rubbers and new wiper spindle seals, but no wiper arm securing nuts so the originals need to be saved. The wiper motor is a DC (direct current) 12V motor that includes a set of gears and a park switch. The park switch allows the motor to stop when wipers are positioned at the bottom of the windshield in their "park' position. There are clips that can be bought that will hold the ball in place in the cup, however these are a short term fix only. Can I supply my own parts?

Evidence:Although these two inner joints (left) attaching the rods to the motor’s crank arm were okay, the nearby gouge showed the linkage had been rubbing against the bulkhead.Cleaning up:The remnants of the old hinge covers are lifted off and the underside of the moulding cleaned smooth, and debris removed from the holes. A problem with the wiper motor park switch can cause the wipers not to turn off or park in random spots. It might happen intermittently, often in cold weather. Some Honda and Acura cars had this problem. The park switch is built into the wiper motor, but in some cars, parts related to the parking switch come separately. In most cars, the park switch comes together with the motor, so if the park switch is bad, the wiper motor must be replaced. Final job:On the outside of each hinge cover are two rubber tongues that need to be carefully pressed downward to locate underneath the edge of the wing panel.

Wiper arms:The wiper arm caps are prised off (using fine screwdriver in slot), and the securing nuts removed. With the wipers hinged up, the arms will wiggle off.First sight:The forward edge of the moulding will now lift up from the scuttle, exposing the wiper motor and part of its linkage here on the driver’s side. If it's possible to free wiper arm shafts out of the linkage, your mechanic may suggest an option to clean and lubricate the shafts without replacing parts. It is cheaper, but the proper solution is to replace the linkage.
