This article supersedes TSB 03-15-06 to update the vehicle model years and build date information.
ISSUE

failure.
ACTION
Inspect and seal cowl area and install Rain-Hat Extension Seal. Inspect and replace blower motor and/or blower motor resistor if there is evidence of water/corrosion. Refer to the following Service Procedure for details.
SERVICE PROCEDURE
1. Access blower motor and resistor per the Workshop Manual Sections 412-02 and 412-04. Inspect for evidence of water/corrosion. If water/corrosion are found or parts have failed, replace per Workshop Manual (blower motor 1F1Z-19805-AA and resistor F6DZ-19A706-AA). 2. Visually inspect the Cowl Vent Screen located under the RH windshield wiper to verify if the screen is fully seated. Inspect the rubber seal on the vent screen which should be fully seated against the windshield. If the cowl vent screen is not fully seated and appears warped, it must be replaced (4F1Z-54018A16-BAA). 3. Remove the cowl vent screen per the Workshop Manual Section 412-01 Pollen Filter Removal and inspect the cabin filter to confirm it is fully seated. Re-seat the filter as necessary. Inspect rain-hat base to make sure it is secure and sealed to the body. Reposition and reseal as necessary using Clear Silicone Rubber TA-32.
