Number 194
Corp. Ref. No. 011523
Date Nov. 1990
SUBJECT: HIGH DOOR KEY EFFORT WHILE UNLOCKING FRONT DOORS
MODELS AFFECTED: 1987-1990 DE VILLES AND FLEETWOODS
Some 1987-1990 DeVilles and Fleetwoods may experience a condition of high key effort while unlocking the front doors. This condition may be caused by the power lock actuator remaining in locked position adding effort to the lock/unlock linkage. To repair this condition on 1989 vehicles built after breakpoint number 222539 and 1990 vehicles, replace the lock/unlock linkage bell crank with P/N's 25557816 (right) and 25557817 (left). To repair this condition on 1987 through 1989 vehicles built prior to breakpoint number 222539, install spring P/N 16602519 to the existing lock/unlock bell crank. Refer to Figure 10-6-19 in the 1990 DeVille/Fleetwood Service Information Manual.
Be sure to check for the proper operation of the power lock system after spring or bell crank installation.
