INTERMITTENT OPERATION OF LOCK WITH REMOTE KEYLESS ENTRY

SUBJECT: INTERMITTENT OPERATION OF POWER DOOR LOCKS WITH REMOTE KEYLESS ENTRY (RPO AU0) (REPLACE LOCK SWITCH)

VEHICLES AFFECTED: 1992 PONTIAC TRANS SPORT

CONDITION:

---------- The power door locks may be intermittently inoperative, or may experience multiple lock cycles at random intervals, on 1992 U-van with Remote Keyless Entry (RPO AU0) only.

CAUSE:

------ The door lock switch circuit boards may have voltage present at the input to the Remote Keyless Entry Module at the wrong time. This condition was corrected shortly after start of production.

CORRECTION:

----------- Since this condition is intermittent, normal diagnosis may result in incorrect parts being replaced. Remove both door lock switches, and check the date codes. The date code has four digits. For example, "1319", where the "1" is the last digit of the year (1991) and the "319", is the Julian date. If either of the date codes is 1319 or lower (older), both the left and right power door lock switches should be replaced, following Service Manual procedures. If both the date codes are higher (newer) than 1319, other causes of this condition should be investigated, following the diagnostic procedures in the Service Manual.

Notice: It is not necessary to remove the door trim panel to replace the door lock switch.
