SUBJECT: AIR CONDITIONING BUZZ NOISE FROM CENTER DASH OUTLETS
MODELS AFFECTED: 1985 ELECTRA AND PARK AVENUE
NOTICE: This bulletin supersedes 85-1-1 dated August 1984 for correction of labor operation number. Please discard original bulletin and replace it with this one..
We have heard of some cases where a buzzing sound may be experienced out of the two center air conditioning dash outlet areas when system is on high blower speed. This condition can be repaired by carefully prying the two center outlets from the duct and removing the horizontal vane that can be seen from the back side. An outlet can be removed by pushing up the center of the lower edge of the outlet and prying outward until the two locators are freed. The vane can be removed by bending slightly until it detaches from retaining dowel holes at each end. (See Illustration) Reinstall outlets back into dash.
Outlets are marked on top with an "L" or "R" to indicate position in the dash. Care should be taken to reinstall with proper orientation. The horizontal vanes were removed in production on 5-24-84.
