Well, its a lil confusing. If I use the driver switch to lock all the doors, I hear the motors but they don't lock. If I use the passenger switch, they all lock and unlock. I'm guessing the motors are find but some of the switches need to be changed? As far as the windows go...the rear window switches don't work but if I use the drivers main switches are used, they work. One day, the main switch didn't work for the right rear window. IDK what I should do. I want to buy what ever I need but I don't know WHAT I need. Also, the rear hatch NEVER locks. I want to put my system in but not until the hatch locks.
