ok so, driver side unlock/lock switch will not work. i press unlock and nothing happens, eccept a whirring noise that keeps getting louder then shuts off. However, my passenger side switch works a little. i will have to tap it 3-4 times to get the door lucks up. I dont think its the actuators because they both go up and down (btw i can lock both doors fine w/ switch) what are some other possibilites?
