# INTERMITTENT HORN BLOWINGWHEN CAR IS COLD

#### SUBJECT: INTERMITTENT HORN BLOWING WHEN CAR IS COLD (REPLACE CONTACT ASSEMBLY/VINYL PAD). VEHICLES AFFECTED: 1989-93 "J" MODEL AND 1992-93 "N" MODEL

THIS BULLETING SUPERSEDES AND REPLACES CORPORATE BULLETIN REFERENCE NUMBER 333202**. THIS BULLETIN IS BEING REVISED TO CHANGE CONTACT ASSEMBLY PART NUMBER 15753782 TO 16753782.

#### CONDITION:

--------- Some owners of 1989-93 "J" vehicles and 1992-93 "N" vehicles may experience intermittent horn blowing when car is cold.

#### CAUSE:

----- This condition may be caused by excessive shrinkage of the contact assembly components when cold. This forces the horn pad contact plates together which activates the horn.

#### CORRECTION:

---------- Install new parts according to explanation below:

On 1992 "N" Models without leather steering wheel and 1989-93 "J" models, the vinyl pads cannot be assembled with redesigned contact assemblies. Therefore, replace with P/N 16753782 (Contact assembly) and P/N 16753781 (Vinyl pad) for these models.

On 1993 "N" cars, only replacement of the contact assembly is necessary.
