Safety Recall: Windshield Wiper Motor Does Not Work (Supersedes 08-013, dated April 23, 2008, to update the information marked by the black bars and asterisks)
BACKGROUND
A breather port on the windshield wiper motor vents warm air from the wiper motor during operation. If water enters the breather port, it can cause corrosion that could make the wiper motor stop working. A non- operating wiper motor increases the risk of a crash in certain conditions.
CLIENT NOTIFICATION
Owners of affected vehicles have received a notification of this campaign. An example of the client notification is at the end of this service bulletin.
Not all vehicles within the affected VIN range have a wiper motor problem. To verify vehicle eligibility, you must check at least one of these items:
^ The client has a notification letter.
^ The vehicle is shown as eligible on a VIN status inquiry.
In addition, check for a punch mark above the fifth character of the engine compartment VIN. A punch mark in that location means this campaign has already been completed.
Some vehicles affected by this campaign may be in your used vehicle inventory. According to federal law, these vehicles cannot be sold or leased until they are repaired. To see if a vehicle is affected by this campaign, do a VIN status inquiry before selling or leasing it.
CORRECTIVE ACTION
*Inspect the windshield wiper motor and, depending on its condition, install a wiper motor kit or a wiper motor linkage assembly. If the inspection shows that a countermeasured wiper motor has already been installed, no further action is needed.*

Defect Code: 5WMOO
Symptom Code: Q7200
Skill Level: Repair Technician
REPAIR PROCEDURE
1. Turn the ignition switch to ON (II), and turn on the wipers:
^ If the wipers work, go to step 3.
^ If the wipers don't work, go to step 2.
*2. Replace the wiper linkage assembly (includes the wiper motor):*
NOTE:
Torque the windshield wiper arm nuts to 30 N.m (22 lb-ft).
^ Refer to page 22-257 of the 04-06 TL Service Manual, or
^ Online, enter keyword WIPE and select Windshield Wiper Motor Replacement from the list.
Once the assembly is replaced, go to step 26.
3. Remove the left and right rear engine compartment covers, the windshield wiper arms, the rear hood seal, and the cowl covers:
^ Refer to steps 1 thru 3 on page 22-257 of the 04-06 TL Service Manual, or
^ Online, enter keyword WIPE, select Windshield Wiper Motor Replacement from the list, and do only steps 1 thru 3 of that procedure.
4. Check the part number on the wiper motor:
* ^ If the part number ends with A020 (see below), a countermeasured wiper motor is already installed; go to step 24.
^ If the part number ends with A011 (see below), go to step 5.*
^ If you cannot read the part number, or if the number is not a part number (2725L, for example), go to step 5.
5. Disconnect the wiper motor 5P connector, and detach the wire harness from the wiper linkage.
6. Remove the wiper linkage assembly from the cowl (four bolts).
7. Scribe a line across the link and the wiper linkage to mark the original park position of the wipers.
8. Remove the wiper motor from the wiper linkage (one center nut and three outside bolts).
9. Look at the breather port on the wiper motor:
^ If the breather port has a splash rib around it, a countermeasured wiper motor is already installed. Go to step 16.
^ If there is no splash rib around the breather port, the wiper motor is a pre-countermeasured part. Go to step 10.
10. Look for rust or cobwebs in the breather port:
^ If the breather port is clean, go to step 11.
^ If you see any rust or cobwebs, install a new wiper linkage assembly, torque the four wiper linkage assembly bolts to 9.8 N.m (7.2 lb-ft), then go to step 21.
11. Clean the surface of the motor case and the sealing area between the motor case and gear housing with a shop towel.
12. Loosen the two wiper motor screws 3 turns.
NOTE:
Do not remove the motor case from the gear housing (the screws come out after only 5 turns). If you remove the case, you could change the position of the magnets inside, causing the motor to run backwards.
13. With the screws still loose, slightly pull the case away from the housing and look inside:
NOTE:
Look inside the case by slightly separating the two halves by hand. To avoid damaging the case 0-ring, do not use a screwdriver to separate the halves.
^ If the inside of the case looks clean, go to step 14.
^ If you see any corrosion, mineral deposits, or water, install a new wiper linkage assembly, torque the four wiper linkage assembly bolts to 9.8 N.m (7.2 lb-ft), then go to step 21.
14. Check the condition of the 0-ring installed between the case and the housing:
^ If the 0-ring is smooth and flat all the way around the housing, tighten the two motor screws, and go to step 15.
^ If the 0-ring is pinched and/or rolled, install a new wiper linkage assembly, torque the four wiper linkage assembly bolts to 9.8 N~m
15. Press the snorkel from the wiper motor kit over the breather port. Make sure the flat-rounded end of the snorkel goes over the breather port.
16. Place the pre-countermeasured or the countermeasured wiper motor in its park position by connecting the 5P connector to the wiper motor and cycling the wiper switch one time.
17. Install the wiper motor onto the wiper linkage using its three outside bolts. Torque the bolts to 8 N.m (6 lb-ft).
18. Move the wiper link into the park position you marked in step 7, then tighten the wiper motor center nut just enough to seat its lock washer.
19. Move the linkage until you can fit an adjustable wrench on the wiper arm link, then hold the link with the adjustable wrench while torquing the center nut to 31 N.m (23 lb-ft).
20. Move the wiper link back to the park position you marked in step 7, then reinstall the wiper linkage assembly on the cowl. Tighten the four wiper linkage assembly bolts to 9.8 N.m (7.2 lb-ft).
21. Attach the wire harness to the wiper linkage assembly, and connect the wiper motor 5P connector. Cycle the wipers one time to get the motor and the linkage into the park position.
22. Lubricate the moving parts of the wiper linkage with multi-purpose grease.
23. Only on vehicles with a pre-countermeasured wiper motor reinstalled:
Install the EPT seal from the wiper motor kit on the cowl flange:
^ Clean the cowl flange area above the wiper linkage assembly.
^ Press the EPT seal into position on the cowl flange, along the base of the windshield.
24. Reinstall the remaining parts in the reverse order of removal. Note these items:
^ Torque the windshield wiper arm nuts to 30 N.m (22 lb-ft).
^ Replace any damaged trim clips.
25. Make sure the wiper motor and the wiper arms work correctly.
26. Center-punch a completion mark above the fifth character of the engine compartment VIN.
