Why don’t my non-driver door locks unlock?

    I have a 2005 Mazda 3 (SP 2.3) with roughly 133,000 miles on it. For a couple of years now, my non-driver door locks have not unlocked properly.

    The problem is when I use my keyless entry to unlock the car, the driver door unlocks after the first press, but the rest of the doors don’t unlock after the second press (I can hear the driver door trying to unlock again, so I know the signal is getting there). Then I open the driver door, and press the switch on the arm rest and none of the other locks unlock. So I have to reach across and manually unlock them.

    This problem has been going in and out, if I had to guess the symptoms seem to show up when the outside temps rise. I know the signal is getting to the locks in question because regardless of the symptoms above being present or dormant, any attempt to lock the doors from the driver seat arm rest switch or the keyless remote is successful.

    Any idea what the root cause might be? And does anyone know how to fix it?
