HELP, i have searched and searched and cannot find the answer to my problem. I have a 2008 Mazda 3, the front door locks do not lock or unlock with the remote or door switches the rear door locks work just fine with the remote and door switches. I checked the fuses under the glove box and they are good. Passenger actuator does not make a sound but the driver door actuator does but still does not unlock, could the passenger bad actuator cause the front door locks not to work. I have no idea what else to do but replace the bad pass. actuator and hopefully that works. i hope its not a harness problem. any body know what else it could be?
