Tesla Motors Club

After searching around, I found the various reboot processes and tried them out to get my touchscreen to turn back on, but none of them worked.

Currently, my car is sitting in my garage, a/c is running and won't shut off. I spoke to Tesla roadside and service. They set me up with a mobile service appointment for Tuesday, which is fine. However, I am worried about the a/c running non-stop like this.

-car is able to drive
-car is able to charges
-just no touchscreen
-no voice commands either
-car doesn't connect to app

Would there be any damage done to my car if it is left with the a/c blowing until my Tuesday appointment? Any ideas on how to manually shut the entire car off until my appointment date?

Thanks in advance!
