Problems with heat settings

Has anyone experienced this:

Occasionally (1 out of 10 times) I cannot change the direction of airflow (window defrost, feat, face, etc) when i first start the truck. Upon start up the heating system will be off, I always leave it in window defrsot 23C and high fan when shutting it off, I can increase the temperature afterwards and turn the fan on high but it stays stuck on window defrost even when showing a different setting on the screen. I usually keep a USB cord plugged into the port for connecting android auto to my phone, it could be coincidence but it seems when I unplug it and restart the truck everything seems to work. 21 Crewmax TRD off road

 

Question - when this happens, does that little screen fail to display anything for about 30-45 seconds?

If so....warranty claim. It's something called the 'servo damper solenoid' or something. If need be I can post a pic of the receipt I got from the dealership. Mine's doing the exact same thing.

 

Thanks Kung,

The screen isnt completly blank, it displays the output setting for the airflow but no temperature or fan speed

 

Sorry, I should clarify...does the little screen fail to display anything *specifically when starting the vehicle*? Mine does the same thing...and I've noticed when it does, I can tell because upon starting the truck, the screen lights up but displays nothing for 30-45 seconds. Evidently it's doing a self-test when it does that.

 

You have the part number for that solenoid?

 

Not off the top of my head, but I can/will look @ the invoice thing tomorrow. If it's not on there I'll call the dealership to get it.
