📝 Wipers that stop mid-sweep or work only sometimes are almost always this board (GM even recalled some years). Swaps onto the motor in the truck with basic hand tools.
⚠️ Verify before buying. Fitment varies by year, engine (4.3/5.0/5.7/7.4/6.5) and 2WD/4WD. Confirm against your VIN/build before ordering.
