Hello everyone I'm new here. I have a 2005 Mazda 3S and I have a problem with left front window of my car, it doesn't go down at all, when I press the switch nothing happens and if I continue pressing the switch sounds a clic on the window but again nothing happens. The weirdest thing is that it happens mostly at the day when the weather is hot or very hot, because at night when the weather is cold the window works just fine? I don't know what to do, I think I'm going crazy with this?

Do you know what it could be ? I read something about a problem with a plastic or something like that on the windows mechanics that doesn't work on hot weathers? Is that true?

Thanks for your comments

 

It sounds like a thermal issue where something (contacts, connections e.t.c.) is expanding in the heat and not getting power, maybe a bad switch or a bad window motor? Only way I can think of testing it is to rip the door apart and put power directly to the motor, if it turns then its your switch, relay, wiring or the ECU for the windows, if not then the motor is probably bad.
