Older Jaguars used a Lucas wiper motor, while newer Jaguars use an Electrolux motor. If you're experiencing some difficulties with the wipers, if for example the windshield wipers stop halfway up the windshield when you set the wipers on "auto-delay," or if they've just stopped working altogether, you'll want to fix the problem. Repairing the wiper motor is done by replacing the module that holds the motor, while keeping the linkage and the rest of the wiper system intact.
Pull the plastic cover off the end of the windshield-wiper arm base. This will expose the 13mm nut underneath.
Unbolt the nut on the wiper arm with a socket wrench.
Wrap the gear puller over the base of the wiper arm and tighten the gear puller to remove the wiper arm. Repeat this process for the other wiper arm.
Remove the six screws that hold the cowl in place and remove the cowl from the base of the windshield.
Remove the three nuts that hold the motor assembly in place and slide the motor out of the cowl.
Insert the new motor assembly and secure it to the linkage with the three factory mounting nuts. The rest of the installation is the reverse of removal.
