Answer
read the following and see if this holds true to you-----16928  1997-2003 F-150 - INTERMITTENT ELECTRICAL CONCERNS
SOME 1997-2003 F-150 VEHICLES MAY EXHIBIT VARIOUS INTERMITTENT ELECTRICAL CONCERNS INCLUDING BUT NOT LIMITED TO: SOME ACCESSORIES REMAINING POWERED UP WITH THE KEY OUT OF THE IGNITION, MULTIPLE SYSTEM WARNING LIGHTS WITH 'SHORT TO POWER' OR 'LOW BATTERY VOLTAGE' DTC'S. IF THESE SYMPTOMS MOST OFTEN OCCUR AFTER A RAIN OR SNOW, OR AFTER THE VEHICLE HAS BEEN WASHED, THIS MAY BE DUE TO WATER INTRUSION IN THE CENTRAL JUNCTION BOX (CJB) OR GEM. TO SERVICE, REMOVE THE GEM AND CJB FROM THE VEHICLE, SEPARATE THEM, AND INSPECT FOR WATER CONTAMINATION OR SIGNS OF CORROSION. IF FOUND IN EITHER COMPONENT, REPLACE BOTH COMPONENTS, THEN LOCATE AND REPAIR THE SOURCE OF THE WATER ENTRY.
