it's possible the relay box is getting old on you. Relays do wear out over time causing a shortage in current/voltage to solenoid...OR, could be simply the motors wearing out...if you have a volt meter, test the INPUT at the actuator itself and flip the switch and see if you find any inconsistency.

CHECK for proper signal/voltage/current at:

output of keyless entry
input at relay box (OEM)
at input of actuator/solenoid

ALL SHOULD BE 12V
