Jealous of your portable A/C. It's crazy hot here (and my never-had-a-problem-in-11-years camry threw a P0430.. yay)
For your door locks, it really sounds like a bad switch more than the actuators. It's hard to believe they ALL have the problem at once. What about the lock/unlock switch on the passenger side vs. drivers side vs. keyless entry... do they all exhibit the same symptoms?
