Auto door lock don’t work when on hot days
LEXUS IS II (GSE2_, ALE2_, USE2_)

My car in hot days doesn’t open all doors, i press the key fob button to open the doors and he only open the driver door, i hear the system trying to work but he always end up opening only the driver door leaving me with the old school work to open manually every other door. I already searched through hundreds of forums and there’s 2 options, door actuator or ecu. I need to be certain of what is causing the issue, i am going to spend money and because i am a guy that cares about the car, need to be sure.

Thanking upfront.
