Alright. I'm still pretty new to this forum but I've been around the internet long enough to know that the "Search" comments are coming, but my issues seem slightly different than others.
We purchased our 2003 LX470 in April and have loved it so far. Since we bought it, the locks/switches/remotes have all worked flawlessly.. Until today. Granted, I probably already know the answer because yesterday and today have been the hottest days of the year so far here in northern IN (90+F). It was hot, so I opened the sunroof when i got to work at 7am. At 4, it was looking like it might rain, so I run out real quick to close the sunroof. I unlock the drivers door with the remote, reach in and close the roof, and then close the door. Walking away, I hit the lock button and got hear the locks click, but no beep.. tried it a couple times and nothing. I came back to find the driver's door still unlocked. Already, I was anticipating having to replace the lock motor.. I fiddled with it for another minute or 2. the switch on the door also has the same effect, nothing. the other doors seem to be working at this point.. I get out, close the door and lock it manually. then hit the button on the remote and still nothing.. I come back again to find the passenger front door unlocked.. Try to lock it and now it's weak.. Ok, that's pretty bad luck right? I cycle the locks again 2, maybe 3 times to see if there are any other issues. Well now none of them work right.. The fronts barely move, the backs sometimes work, but not consistent and after I manually locked all 4 doors, I still couldn't get the alarm to chirp with the remote.. Then I find the rear hatch unlocked.. WTF?? It also had to be locked manually, and once it was, the alarm chirped like it should using the remote..
So what gives? Was this just absolutely terrible luck? I could see 1, maybe even 2 giving out at the same time, but all 5? the results were the same using the remote, as well as the switches on the doors, so I don't think either of those are the issue, and I started the engine and tried to cycle the locks with the same disappointing results, so I don't think it's a voltage thing either.
Am I correct that it's probably a combination of the heat, plus me cycling the locks more than once in a short period of time that killed them all? Bad luck? Or is there something else underlying that I should check?
