Temperature Sensitive Door Locks

I have a 2000 Lexus RX300. The drivers side doorlock works fine when the temperature is at or below freezing. When the outside temperature warms up, the door lock will only work intermittently.

Any ideas what is going on??

You may have a loose/corroded electrical connection to the window motor.

Drivers door is pretty much always the first to go simply due to use.

You’ll have to remove the door panel and do an inspection.
