I put an aftermarket alarm in the vehicle and all was working fine, 2 days later locks start acting up. First the passenger rear door would not unlock, then every now and then all doors would not lock, now weather I use the aftermarket or factory keyfob, button in door or manually control the locks via the lock or key....nothing. I hear the relay clicking but nothing. So the signal is obviously getting to the BCM, but not back to the motors. If I don't get a answer I am going to go into the doors and start trouble shooting. Pretty sure the aftermarket alarm is not the problem, I disconnected it and no change.
