i've tried taking off the door panel off and checking the wires out, but the thing is, when i use the remote or the button that automatically locks and unlocks the car, the locking part doesn't want to lock. i guess the solenoid, or whatever they use to push and pull that wire that locks and unlocks the door doesn't have enough power to push (which locks the door) but when i remotely unlock the door it unlocks fine. i'm trying to find a more easy way then going to the dealership and having them fix it, i guess my warranty on the doors are voided since i put vertical doors on, according to the dealership. i'm just looking for possibly a replacement part for the mechansim that operates the locking system. is there anyone else out there that have had this problem or know how to fix it. again, i know for sure that the cable is not loose and it is on the correct way, there is something wrong with the actual locking mechanism.
