Affected:
1988-1992 SUNBIRD CONVERTIBLE SERIES
Replacement of the hydraulic lift cylinder should not include replacement of the hydraulic motor and pump assembly unless it has been determined the
motor and pump assembly is malfunctioning. Investigation of returned field failures of motor and pump assemblies show that the problem is with the
hydraulic lift cylinder only and not the motor.
The correct procedure for checking the hydraulic lift cylinder and the motor and pump assembly can be found in the Service Manual.
