Model 3 rear fan won't stay on!

[kelvin 660]

I've recently noticed that the rear fan is not blowing cold air and that I have to go into the HVAC screen to turn it on. However next time I get into the car it will be turned off! I'm sure it used to blow cold air when the seat belts are plugged in (which they all are). So now our small dog is getting very hot, if we forget to check if the air is blowing...
Anyone know of a work around for this problem as it's getting annoying to have to go into the HVAC screens to turn it on?

I think it has weight sensors in the rear seats and only turns on the rear fan when it senses a passenger in the back. Not 100% certain but that's how it seems to work in ours.

Mine is the same but also air doesn’t come out of the front passenger vent unless the seat is occupied. I think it’s an energy saving feature
