I would like to use the climate system to keep the car cool for a few minutes while I run into a store and my dog is in the car. I have tried both the app and the key fob and it did seem to work one time. The app always says the temp is 75 in the car. I have it set at 68 or less but if I let it go 10 min and get in the car is quite warm so I have no confidence in it...but love my Clarity in all other respects!! Any thoughts on keeping my dog cool?
