  • NOISE – “WHINING” IN AM RADIO BAND – VEHICLES BUILT THROUGH 5/30/97
Publication Date: JUNE 23, 1997

LIGHT TRUCK:
1997 EXPEDITION, F-150, F-250 LD

ISSUE:

There may be a “whining” noise heard through the radio while in AM band below 1100 kHz with the A/C temperature control at Full Cool or Full Heat. On vehicles with rear A/C units, the rear temperature or mode controls may be at any position. In some situations the noise may change when vehicle loads are switched on and off. This may be caused by electromagnetic interference from the blend door actuator.

ACTION:

Verify condition and replace the front and rear (if equipped) blend door actuators. Changing the position of the temperature or rear mode control will eliminate the noise and verify the condition exists. The new actuators have been revised to reduce potential electromagnetic interference which should reduce the possibility of whine heard through the radio. Refer to the 1997 F-Series or Expedition Workshop Manual for removal and installation procedures.

NOTE:FOR EXPEDITION ONLY: THE EVAPORATOR ASSEMBLY MUST BE REMOVED TO GAIN ACCESS TO THE BLEND DOOR ACTUATOR. FOLLOW PROCEDURE OUTLINED IN THE 1997 EXPEDITION SERVICE MANUAL, SECTION 412-03.
