Power door locks inop
Recently the front passenger door lock on 2004 LS430 became inop. Now the driver door lock is also inop. Back door locks work fine. I have purchased door lock actuators to replace the front ones. However, one repair shop stated... "WE WOULD NEED TO PERFORM A DIAGNOSTIC CIRCUIT CHECK OF POWER LOCKS TO DETERMIN IF IT’S A POWER OR GROUND ISSUE , OR IS IT A SWITCH =OR ACCUATOR ?? ONCE WE DIAGNOSE IT WE CAN GIVE YOU A ESTIMATE TO REPAIR , DIAGNOSTICS GENEALY RUN $ 100.00."
I'm tempted to NOT have the diagnostic circuit check done since failed door actuators seem to be a common problem.
Any comments/recommendations appreciated.

jdixp2: Each door has a computer which distributes electrical power to each door mounted device as needed. If your mirrors, mirror heat, illumination lamp, and power windows are all working, then the power and ground to the "door ECU" is satisfactory.

Well my problem is getting worse. Everyday occurance. Problem doesn't happen in the morning since I can unlock and lock all doors ok...only happens during the day. My 30 second wait theory doesn't work. Maybe it is heat related since it's darn hot here and my car is black. I'm still investigating and experimenting.
What's confusing me is since the locks do work ok in the morning, what's causing them to act weak during the day?

a door acuator is one unit and it locks and unlocks your door. there is one acuator per door. this is a very common problem gs' and by doing a seach, you'll get a lot of info.
most cl members buys the acuator from carson toyota and have their mechanic do the job. you can do it yourself but it's a bit complicated and you need the right tools so it's better to pay someone.

Right side door locks
I have the same problem. My mechanic says both actuators are bad, $1,000 to replace. Why should BOTH actuators on right side go bad at the same instant in time? Occasionally one or the other will lock, but usually I have to manually set the locks inside then close the doors holding the handle out. Could it be something other than the actuators?

I repaired mine with the little $5 replacement motors that you buy on Ebay.

I have a 01 GS430, the motors should be the same in all models right?

All 4 of mine are out now lol. For some reason, the rear passenger was not locking even when I tried to manually lock it. I ended up putting the child lock on, which worked and kept the door from opening up. However, now that I think about it, that might have been a bad idea, because I can't open it from the outside or the inside....... What do I do?!?!?
BTW if there is anyone in the Austin or Houston area that has experience with this and can do this for me, I will pay you.

my driver side actuator went in and out for a while then finally conked out..since its the driver side it is a pain in the **** but tolerable..few nights ago the pass rear started acting up..i think there's a larger issue looming though and may need to replace the wire connecting to the battery. i picked my gs a few years back and it had only 12k miles on it so it sat with the prior owner. battery acid really tore it up and when i went to change the battery, that was when i noticed the issue. I'll have to figure out if there have been prior posts on this issue
