What techs usually find when diagnosing B2289 on specific vehicles — tap your vehicle for the fix and the exact part:
2005-2015 Chevrolet/GMC Trucks Moderate DIY
B2289 windshield wiper control on GM trucks points to the wiper motor park switch or the BCM's wiper control circuit. Remove the cowl and test the wiper motor with direct 12V -- if it parks correctly, the issue is in the BCM or wiring. Multi-function switch on the steering column is also a common culprit.

Ford sets B2289 when the wiper motor module loses communication or when the wiper relay in the BCM fails. Test wiper fuse (usually F37) first. If the wiper module has integrated electronics (later models), replacement is required -- Motorcraft WM-658 is the OE unit. Park position is learned by the module automatically.
Labor: 1-2 hours2007-2015 Nissan Altima/Sentra Moderate DIY
Nissan B2289 is commonly a multi-function switch failure on the steering column -- the wiper stalk's park circuit fails internally. Replace the combination switch (Nissan 25560-zx00A for Altima) and code will clear. If switch tests OK, the IPDM relay may need replacement.
