Step 1. To access the module, the plastic cover under the windshield wipers must be partially removed. a. Put the hood in the completely upright position. b. Remove the 2 plastic cover caps ( If you still have them ). c. Remove the 13mm nuts by holding the wiper arms. d. Place the wiper arms in the upright position, gently rock the part on the knurled stud up and down until it comes free. If this doesn’t work, you will have to use a small puller. e. Remove the fastening screws, push down on the 2 metal harness clips to free them, cut the 2 tie wraps. ( you’ll need 2 new ones for the reinstall) f. Wiggle the cover free and disconnect the wiper spray heater connector. You can now position the cover out of the way. Step 2. Unplug the alarm module in the center. Clean your drains while you are in there.
