I ask this question because my pass. side actuator has been making a buzzing sound for the last year...The doors still lock, but it's just noisey when unlocking...So today I tore out the actuator and disassembled...What I found were some broken bits(gear pin and some other little plastic things)...So now I know what the problem is, going back to my original question, can I use the guts from drivers side spare and swap them into passenger casing...Or, could I just use whole drivers side unit altogether...Once i tore into actuator, it's pretty easy looking to clean/assemble...I'm use to working with R/C trucks, so they are basically the same(plastic and gears and motors)...Any help would be appreciated...
