Ok.. I see a few other door lock questions.. but have never seen the solution..

Problem: 2004 Camry SE, key fob or door switch will not open the 3 passenger doors when the vehicle get warm.. ( I live in Fla).. In the morning and well after dark everything works fine.. I am always able to open the drivers door.. It is the passenger doors that I am having issues with.Once the cars tempeture and I mean the cabin temp get up to about 90 to 100, sitting outside.. the 3 passenger doors need to be unlocked manually..

Any help would ge greatly appricated..
Thanks,
Jim

 

Do a few tests as to what works and what does not.

Is the issue the car or the key fob being hot? When hot do the individual door controls work, can you unlock all doors with the key and if so do both drivers and passengers key unlock sysems work?

The lock system is controlled by the Body Computer located behind the drivers side dash where your left knee would be. Might get a can of cold spray, spray electronic repair folks use to cool electrical components during testing. When the system is hot and not working spray the computer to cool it down and see what happens.

Or could be bad wire connections, it gets hot and they expand.
