Condition
Some customer's may comment that the windshield washer pump operation is intermittent.
Correction
DO NOT REPLACE THE WINDSHIELD WASHER PUMP.
Engineering has determined that windshield washer pump intermittent operation or poor performance conditions may be corrected by replacing the current 10 amp WSW fuse with a 15 amp fuse. The WSW (windshield washer) fuse is located in the UBEC (underhood bussed electrical center).
Important:Be sure to update the UBEC fuse label to indicate the use of a 15 amp fuse for the Windshield Washer (WSW).
