How to Replace Windshield Wiper Transmission Linkage 02-06 Nissan Altima

Difficulty: Intermediate · About 90 min · Nissan Altima

Replace the windshield wiper transmission on a 2002–2006 Nissan Altima by removing the arms and cowl, transferring the motor, then checking the wiper park position and sweep.

Steps

1. Mark and remove the wiper arms

   Set the blades in their parked position and mark their locations on the glass. Lift the bolt covers, remove the 14 mm nuts, and rock each arm loose from its tapered spindle.

2. Remove the cowl panel

   Pull away the cowl weatherstrip and retrieve any clips left behind with needle nose pliers. Release the cowl rivets and wiring clips, then lift the panel clear of the vehicle.

3. Unbolt and disconnect the linkage

   Remove the fasteners securing the transmission and its bracket. Take off the bracket and harness cover, unplug the wiper motor connector, then lift the complete linkage assembly out.

4. Transfer the motor to the replacement

   Hold the motor crank steady while removing its retaining nut, then separate the crank from the motor shaft. Remove the motor screws, move the motor onto the new linkage, and reinstall the crank, washers, and nuts in their original orientation.

5. Install the replacement linkage

   Lower the assembly into position and secure its mounts and bracket. Reconnect the motor wiring and refit the harness cover, routing the wiring clear of moving linkage parts.

6. Refit the cowl

   Set the cowl back into its locating edges, reinstall its clips and rivets, and press the weatherstrip evenly onto the panel so it seals along the windshield.

7. Align the arms and test the wipers

   Fit the arms to the marks made earlier and tighten their retaining nuts to the vehicle specification. Reinstall the caps, run the wipers through a full sweep, and confirm both blades park without hitting the trim.

Check your vehicle’s repair manual for exact specifications and fit.
